Dead Letter Branch Cover From 1947 With Postage Due Stamps

I have a US cover from 1947 with 5-cents of postage due stamps (see image). It was mailed from the Miami dead letter branch to the sender. The reason is listed on the envelope: "A letter without the sender's card address on the envelope is charged with this fee for return."

My assumption is that the sender's letter could not be delivered and was forwarded to the dead letter office for handling. Is that a reasonable assumption?

Since there no return address on the envelope, it was opened and that was when a postal clerk found the sender's address on the letter (which I also have). At that point, the letter was placed in an official envelope, 5-cents of postage due stamps were affixed, and it was returned to the sender. This part of the story I'm fairly confident in based on the 1948 edition of "Postal Laws and Regulations," p. 370, Section 45.9(b).

By the way, the letter sender was John R. Schott of Cleveland Heights, who was 11 years old in 1947. He went on to have an illustrious career in academia and international affairs and passed away at age 82 in 2018.

Thanks in advance for any feedback.

Very nice. Yes, I agree with your analysis, although the 1940 PL&R volume would still have been in effect in 1946. For those interested in the text, Sections 821 and 822 of the 1940 PL&R are:


The entire PLand R book was renumbered in the 1948 edition to become sections 45.8 and 45.9 as noted in the original post, with only slight text changes not changing any real meaning or procedure.

The "Miami 31, Florida" portion of the return address utilizes the Zone Number instituted in mid-1943 in about 120 cities, and based on Boston's zone system in use since 1920, later expanded nationwide in 1963 to become the Zip Code, but I digress.

To digress again, note the two due stamps have been precancelled with a parcel post style roller cancel rather than a standard precancel device.

Here is brief presentation on Dead Letter mail history and handling that I did.
