The Subject Is Air Mail Overprints!

Here is one that started life as Spanish Morocco Scott # C5 and after overprinting became Cape Juby Scott # C5.

Isn't it wonderous how a mere overprint can magically turn a regular stamp into an airmail

US in the Philippines



aren't the perfs on the right side unusual on this next one?

Can I fly just a little bit, too? Not exactly an overprint but close.

Colombia produced a nice lot of these:

Revisiting this thread, here's an example of an overprint turning an airmail stamp (1931 Newfoundland SC#C9) into an regular postage stamp (1933 Newfoundland SC#211).
L & S stands for Land & Sea. According to Unitrade this had a print run of 70,000, and all were sold out on the first day they were on sale.




The double vertical lines are supposed to obliterate the words Air Mail, but the overprint has shifted. I wonder if this would qualify as a 211ii (overprint badly shifted).

What a great thread ! I love covers and overprints !!

Here is a Canada C3 overprint used on a First Official Flight.

I specialize in airplane overprints and have compiled a list from the Scott and Sanabria catalogues. I would be happy to share this Excel Spreadsheet with any who are interested. The only caveat is that if you know of an airplane overprint that is not in my list, please let me know. I am researching the overprints and trying to identify the type of aircraft that are depicted. Of course, some are simply caricatures.

...and I have a PDF color scan of my collection. The file is very large so I don't know that I can send it as an attachment. If you are interested, let me know and I am sure that we can work something out. It has many more items that are not depicted on this site.
