Hello All,
As you know most times finding things at an antique store is very hard to do and if you find anything it's really expensive even for dead common and damaged items. Occasionally, you do get lucky and the price cannot be beat. Yesterday was one of those days.
I was able to find five interesting Asian covers from the late 1940's - three from Japan, one from Thailand and another from Korea. all sent to the Massachusetts Institute of Technology.
Japan cover #1 - They missed a few in the cancelling process, but none the less still very nice.

Japan cover #2 - nice full set of the Yoshino-Kumano National Park stamps plus others.

Japan cover #3 - Scott 457 from the souvenir sheet and block 421a plus others. (March 26th - just noticed a had a link error! duh!)

Registered Trang, Thailand / Siam cover
Front - Nice strip of four on front, but...

Back - ...28 more should do the trick.

Registered Korea cover
Front - Scott 94a in top corner. Sure lot of stamps on this cover.

Back - But wait! There's more! That's a lot of Scott 79.

Scott 79 shows a Tortoise Ship, 1st Ironclad War Vessel.
