A Grandma Moses print is almost certainly a mass-produced photomechanical print. Museum bookstores and online sellers sell them for prices in the general range of $10.00 to $38.00.
Grandma Moses, whose real name was Anna Mary Robertson, painted with everything from oils to house paint. She did not, however, produce original prints, which can be considered investments and have a level of status that mass reproductions lack. Made from a matrix using a single metal plate, such prints are done on stone blocks, wooden blocks or screens. Each impression is done by the artist or artisan, and the matrix is then destroyed. Such prints are traditionally signed and numbered in pencil by the artist.
