Del Ray (Raymond Petrosky). Four of Del Ray?s ?Little Willie? Card-Finding Mice. 1980s. Four imitation novelty mice made of real fur ? three white, one brown ? owned by Del Ray and meant for use in his effect where Willie revealed a card chosen by a spectator. Sold together with a name plaque of Del Ray?s, and the plastic carrying case for the mice. Mice are unprepared. Del Ray interacted with a number of apparently inanimate objects in his classic magic act. That these objects became animated and integral to the unique connection he was able to make with audiences is a testament to his abilities as an entertainer. The interplay between Del and Willie was at once humorous, endearing, and amazing.
