O
nce I started getting obsessed with mail art it only made sense to buy as many oddball rubber stamps I could find. And I have plenty - over 100 in my collection so far, the majority of them bought on eBay. You can find some really amazing rubber stamps on sale on online auctions, just be careful not to get caught up in the bidding frenzy and buy a big stamp for $13 when you can get it at your local stationary store for $9. Or if you want a HUGE selection of interesting and weird stamps, I suggest 100 Proof Press.
