Does everyone posting these here collect them?
I collected stamps as a kid, including a few post cards and other covers, but haven't actively collected since then. I do pick up a few things here and there, for example as souvenirs while traveling.
A friend found about 3 shoeboxes of these really old postcards being sold individually by an antiques dealer at a street fair awhile back (not a garage sale as I previously thought), and bought the lot for something like $20-30 (I think that's why the ones I post have prices penciled on them). From what I can tell most of them are what's left of what must have been a single huge collection, plus a handful of newer cards.
The postcards I collected myself were issued by the post office with stamps pre-printed on them.
