Jimbo,
So you think you're done, eh? You've got EVERYTHING for an airmail collection, right?
Not so fast, me bucko! Having completed the basic album of material, now it's time to go what I call "in-depth" with the collection. Hang onto your seat, 'cuz here we go!
- You've already added plate blocks, but how about engraver/siderographer initials? Here's an example:

You can find these on the earlier stamps through the 1930's issues. The practice fell by the wayside in the 1940's with WWII and never was resumed.
- Add the preproduction material. One of the methods used by the USPOD in the 1920's through the 1960's was photographic essays. This allowed the artists at the BEP to create one image, have it photographed and then passed to the people who needed to see or approve of the design. Here's a couple of examples. I've included the actual stamp for comparison:





You can also add the various ways the USPOD notified everyone about upcoming stamps. Through about 1950, the 3rd Assistant Postmaster General would issue a notice, like this for the the Airmail Special Delivery stamp, Scott CE1.

Another way it was done, for a brief period from 1938 through 1947, was with a card notice. Collectors, first day cachet makers, or whoever wanted to could sign up and have these notices sent to them. Here's an example:


Then, starting around the 1930-1940 period, the USPOD began providing photographs of upcoming stamps to newspapers, cachet makers and magazines. This is an example of what is called publicity photos:

As technology advanced, the USPS add color transparencies. Here's an example of the stamp and both the publicity photo with the publicity transparency:



These are not to be confused with some of the photographic essays, which closely resemble the finished stamp, such as this example for the 20 cent Transport stamp, C29:

You could also add some stamps which were never issued. Here's two nice items.
The first was an airmail stamp which was supposed to be issued for the Inter-American Conference in Quito, Ecuador. Problem was the conference was postponed, as was the stamp. Although announced in October 1959 with an issue date in February 1960, it never happened. Four plates were created, certified and then defaced in 1962 without ever having made an impression! Here's the only tangible evidence of the stamp that never was, the publicity photo:

Another set is shown next. This was a series of designs created by Alicia Kessler. These are the original designs on card in black pen. These were featured in a 1936 Airmail Society Journal article.








You could also add the post office bulletin sheets which the USPOD used between 1960 and the change-over to the USPS in 1971-72 period. Here's an example:

Postally used items - not FDC - are a nice addition, showing the stamps fulfilling the purpose for which they were meant. Here's a couple of colorful examples of airmail stamps used commercially and in the period of the stamp's use:



Exotic uses are always attractive. Here's an example from a sailor on Midway Island, less than a year before Pearl Harbor was attached.

You could look into adding some of the Foreign Air Mail route covers. An adjunct to that would be the photographic essays for the cachets which required USPOD approval. Here's a couple of examples of those:


An interesting type of collateral item is the deck cards for the blocks of stamps. Each "brick" of stamps would have a card cover explaining what it was on top with a black card on the bottom. These have been in use for decades, at least. My earliest one is for one of the Overrun Nations issues of 1942. The more modern ones are a little easier to find, but still a challenge. Here's an example:

If you still need something to add to your burgeoning airmail collection, you can add programs and first day covers. Here are examples of each. along with the stamp they represent.



The final item up for consideration are the USPOD/USPS issued souvenir pages. Here's an example:

So, when you get this finished, let me know and I'll add a few more items to your collection list!
