Kaye, however, in addition to oils, created etchings, watercolors, and pastels, some including currency but others on varied themes.
He began painting trompe-l'œil oils in the tradition of the great 19th-century artists, William Harnett, Peto and Haberle.
In addition to money, Kaye's works sometimes include pistols and musical instruments and almost always show puns and humor.
Beginning in the 1980s his works were sold at galleries and auctions in New York and quickly moved into public and private collections.
Kaye's paintings and prints have been included in museum shows of American art in the United States and recently in Florence, Italy.
