Postal Mistakes In The Shawshank Redemption

Relative to typical movie depictions of mailpieces, The Shawshank Redemption gets an above average grade.

This postcard from Andy to Red (fair use screencap) was created for the 1994 movie. What postal mistakes can you find on it?

Looks like Andy used a 3 cents Sc #656, issued 1954. But the first-class rate was 5 cents in 1966. I am impressed with him using the ZIP code barely three years after its introduction.

Near the end of the movie, Andy mails the ledger and files to a newspaper reporter at the Portland Daily Bugle. The package has three 5¢ "Crusade Against Cancer" stamps (Scott 1263) and four 13¢ John F. Kennedy stamps (Scott 1287) for a total postage of 67¢. Not sure of the weight of the package or if the postage was appropriate.

The stamp in the first image looks like it not a real stamp (printed image) and pasted on the envelopment.

The 3 cent Liberty stamp appears to be imperforate.

The top, left, and bottom are perforated. The left, is not so clear.

here's a zoom into the upper right corner

according to https://about.usps.com/who/profile/...nce-1873.htm the postcard rate at that time was 4 cents, not 3

I believe there are multiple other errors and improbabilities

It's more obvious it is a postcard, so no need to mention letter rates.
It's been noted the postcard rate in 1966 was 4c (correct).
It's been noted the stamp looks imperforate.
Well, the scale (size) is too small, but there was a genuine imperforate 3c Liberty stamp issued and sold by the USPO in the late 1950s...
Speaking of the past (before 1966), this movie item looks more real that most would think. (I haven't seen the movie, so I am assuming the mailer was a current or former prisoner.) Since most of you likely forgot about the genuine imperforate 3c Liberty stamp, I figure a few of you have also forgotten about a stamp-size imperforate 3c Liberty also issued and sold by the USPO. And let's recall that some mailers actually cut out these stamps from post office sold postal cards and tried to use them as stamps on envelopes (sometimes successfully, sometimes caught as invalid postage). The movie prop is a pretty realistic late use (1c underpaid) 3c Liberty postal card, or a prisoner taking a post card and affixing a cut-out of the stamp from an old 3c Liberty postal card.
It only takes a movie character who was in prison for awhile and either did not know post card rate in 1966 and/or was scraping by with materials at hand to create the mailpiece.
[Edit add:] I realize this is stamps forum, but coins forum is nearby and many of us likewise collect coins. This thread reminded me:
I didn't watch the "Bones" TV series (FBI forensics team and FBI agents, etc.) when it originally aired on the Fox TV network in U.S. ... but I happened to see a syndicated re-run years later, that involved a coin collection. It was a point in the story that the collection "ended" in the 1950s, but guess which one coin was held up for a clear view to the viewers? A Kennedy half-dollar! (First minted in 1964.)

The ebay listing states it is a replica of the one used in the movie. The seller claims it replicates the original prop in all details. It does give some information as to what it is supposed to be.

Interestingly, the seller claims the card carried a message. With a picture on one side and only an address on the other, that is strange.
Also, the stamp on the ebay listing appears to have been die-cut.

So, is it really such a good replica?

The lack of a handwritten message is part of the story. imdb users rank Shawshank (basically tied with The Godfather) as the #1 movie of all time. It's worth seeing.

The postcard's cancellation is specifically mentioned in the movie. Several things don't look right about it, but my knowledge of 1966 machine cancellations is not deep, so feel free to correct me. "Fort" uses mixed case letters whereas HANCOCK does not. Texas is spelled out rather than the TX postal abbreviation. The killer bars look too short, as if the time/date circle was moved to the right so as to be clear of the red Riley. The time is marked as AM but PM was more common by far.

I did some searching online and found no machine cancels with city/state names in mixed case letters. Additionally, all the 1960s Texas machine cancellations I found used either TEX. or TX for the state name.

Given that it's not clear whether the stamp has perforations, I began thinking it may have been cut from a FIPEX souvenir sheet. That version is larger than the 3c Liberty definitive, and to me the stamp on the postcard in question looks large, so I decided to count pixels. That count says the stamp occupies 23.5% of the card's vertical pixels. If the postcard is the standard 4" x 6" size, that makes the stamp slightly less than 1 inch in height. The FIPEX version exceeds 1 inch, whereas the standard definitive is slightly less than 1 inch. So, by size, that 3c Liberty appears to be the common definitive. That screen cap is from a standard definition version of the movie. I'll have to watch an HD version to see if perfs become visible.

I agree with classic_paper that the use of ZIP code is surprising. I think businesses were using the codes by 1966 but individuals typically were not yet. There is a logical reason within the story, however, that the card's sender would know the prison's ZIP code, but the details could be considered a small spolier.
