That sounds really neat! I bought a big box of them from a stamp company and it came in the mail yesterday. I have been picking through it slowly, it is kind of a nice little break for me when DS is playing by himself... he will fortunately leave me alone long enough to go through a few things! The stamps from 1930-50 are really neat, how cool that you got so many of them!
I'm not sure collecting stamps is a very popular hobby, but I sure enjoy it!
