Here's a checklist I've compiled of ceramic items by Sigma. Mostly from Tomart's, as well as my own collection. I don't own any of the non-mug/figurine sigma items, so I'm not aware of variations or how to tell some of them apart. I've also included a list of Ceramic mugs by Applause and NECA. If yous e any errors, let me know. I'll update as I come across other info.
