I used to collect leather bookmarks and postcards, both from zoos and anywhere else I visit. I've noticed not many places sell them anymore and I haven't added to my collection in a long time. Does anyone know of any second-hand sites I could buy zoo stuff from other than Ebay? UK based. Especially interested in Twycross Zoo items.
I also collect zoo postcards (especially early ones, the older the better). Delcampe is another website that sells old zoo postcards; it is good for postcards from continental zoos but also sells UK zoo cards too. See link below Delcampe - The collectors' marketplace
When I had a huge beluga whale obsession — which has decreased since — I had 3 different postcards with belugas on it from seaworld San Diego.
