The figures were pictured in a Disneyland brochure dated 1986--but which was issued with the park's 1987 "Summer Program" handout. It was the year of the Snow White 50th Anniversary celebration. See more of the brochure and program at Vintage Disneyland Tickets.

Special thanks to François Monferran for letting us know about these figurines. See an earlier post with cameo heart-shaped boxes which were also produced by StoneQuarry.
