This is a green Anchor Hocking, Colonial, aka Knife and Fork pattern, luncheon plate. This pattern was manufactured for only two years, between 1934 and 1936. This piece fluoresces when placed under a black light.
I have eighteen (18) of these luncheon plates for sale, each one separately. They are all in very good condition, Take a look at the pictures, and if you have questions, please e-mail.
Also, I will gladly combine shipping charges if you buy multiple pieces.
