I just visited the post office today and noticed a new series of stamps called American Advancements in Aviation. Apparently, they have been available since late July, but I just noticed them now (so forgive me if this has already been discussed).
Of the 10 aircraft shown, I was surprised to see seven of them being warbirds: PBY, F6F, P-47, P-80, B-24, B-29, and the YB-49.
Out of curiosity, have the B-17 and P-51 already appeared on American stamps in the past (thus explaining their exclusion here)?
Anyway, they make for a nice set of stamps for warbird fans...
