You can use that 'search the photo guide' for all kinds of specifics about a figure like brand, year, series, name, part of a name, variation, stores that had exclusives, and more. * It does not search the items that are for sale. More guide photos and details are added every few days. That other search way up on the top searches the rest of the site including the store items.

***The "Shop" portion is a new system. That link up there will take you to it.

***The long awaited Batman section has been added!
