In 1980, P. Matthew Monahan and Katherine Keskey were married and had their reception at the Gotham Book Mart. Mr. Monahan was the director of the GBM gallery. Edward Gorey created the invitation for their wedding/reception. As far as I know, this is the only time Mr. Gorey designed a wedding invitation, and it is a scarce piece of Gorey ephemera.
The front of the invitation features a portrait of the couple's cats Fletcher and Zenobia lounging on cushions. I have been told that the cats were named after the characters in the books by Edward Gorey and Victoria Chess (see the posting from March 9, 2009). What I like about this drawing is that the cats are not stylized, but the drawing is an actual portrait of the couples feline companions.
