Back in the day on DeviantArt, I used to be stamp obsessed, so I'm happy that even after that site has gone downhill, that stamps are still relatively popular and that I still have a place to keep my collection.
I really care about crediting everyone who creates graphics, so almost all of these should link back to the original sources. If you notice one that doesn't and you know the source, please message me! I have spent a lot of time browsing websites, DeviantArt, and even the Wayback Machine for sources, but sometimes these things are lost to time. (｡•́︿•̀｡)
