Steve de Brun of Squirl wrote to us about his website (still in beta), which allows users to showcase their collections online (and to meet people with similar interests). Squirl is a freemium (free for the first 200 items, but you have to pay to be able to display more).
This one above is Sigfried's collections of cigarette packs, of which he has over 2,000 from all over the world.
Visit Squirl to find out more: Link - Thanks Steve!
If you like cigarette packs, Igor Sergeev probably has the largest collection: over 20,000 packs.
