Since originally publishing this post, a friend generously gifted me with the two buttons I was missing from Edward Gorey's Cape Cod theatrical productions. The revised post follows:
Edward Gorey created pinback buttons for most of the theatrical entertainments he was involved with. He also created a number of pinback buttons for the New York City Ballet. These buttons were usually made in very limited quantities and were sold in lobbies and gift stores at the events. Extra buttons were usually sold by Gotham Book Mart. Even though they were inexpensive souvenirs, they can be quite difficult to find today, making them a challenging collectible to acquire.
Mr. Gorey usually drew a unique image for the pinback buttons, making each button the only place you will find the image. If the image also appeared on a program or poster, he would redraw it to size for the button rather than reducing it down. Each design is a vignette that often includes the title of the production it was created for. Below I am showing a complete collection of the buttons from his productions on the Cape.
From 1994 onward, Figbash makes frequent appearances on the buttons, as well as on posters, programs, announcement cards, and even on stage. I own one of the earliest white hand sewn Figbash dolls that was included as part of the set decoration on Chinese Gossip.
