From a large estate collection of TV and movie memorabilia, a Fan Art piece ordered from Etsy:  the Spell Disc from Constantine, City of Demons.  This Magic Spell Disc is laser etched on bright yellow lucite (?).  Still protected by the original brown paper backing to protect the surface from scratches during shipping and handling.  Once removed, the etching in the transparent yellow/gold surface will mimic the special effects of the original magic spell disc, especially if you hold a light behind it.
