Frank - You might contact Handwork in Ithaca, NY. I don't have
phone/e-mail for them, but I expect you can get these via Google.
Handwork is a cooperative gallery which is about 30 years old. It is
one of several "spin offs" from the original Ithaca Cooperative,
which include a cooperative grocery and one of the oldest (1972)
farmers' markets around.
