This is a ticket (at least half of one) to Segaworld London! It's rare, because its a paper most people throw out after their visit. Naturally, it has the Segaworld logo (notice there's a pin that looks just like that graphic) & also has a sort of 'shiny effect' for the stock Sonic art. This cost 14.90 pound to get in, & was sold on Dec 12 1998. It's interesting to see as it's so uncommon /forgotten, plus now you know how much a visit cost while it was open.
