Unique collection of four vintage spontaneous pencil sketches and one signature by American illustrators, obtained while they were dining at the Palm Beach Biltmore’s restaurant in February 1940. Three sketches are on the reverse of the restaurant’s 7 x 10.75 cardstock menu: Rube Goldberg’s signed and inscribed humorous restaurant scene, drawn during lunch; Ham Fisher’s signed and inscribed portrait of Joe Palooka, drawn during breakfast; and Billy DeBeck’s signed scene featuring Snuffy Smith, drawn at dinner. The fourth sketch is on the reverse of a blank 4 x 7.5 meal order form: Arthur William Brown’s signed and inscribed portrait of an attractive woman in profile, one of his most famous subjects. James Montgomery Flagg also signed in pencil on the reverse of a 7 x 10.75 cardstock dinner menu. A noticeable diagonal crease through the Goldberg sketch, and general scattered toning, otherwise overall fine condition. Accompanied by a presentation album containing various articles about each illustrator. RR Auction COA.
