- stickers (especially the ones on fruits)
- stamps (another form of sticker)
- photos
that's basically it. anything else is just incredibly wasteful. yes this was inspired by the stanley mugs.
I started collecting postcards a couple of years ago, and I now have two photo albums filled with them! They’re from all over and many of them are gifts from others as well. I also tend to use them as wall decor! My favorites are all pieces from art history—one of my favorite disciplines of study as both an artist and a historian ;) most bookstores sell them, especially used bookstores! They’re a really fun item to collect as they each hold geographical and contextual significance in different ways!
