This old pie tin is circa 1930's, is 10 1/2" diameter circle with 8 sides inside for equal sized slices of your favorite pie. Tin is thick, in very good vintage condition, no dents or rust, bottom is flat. It just has the look of old tin. In researching I never saw another 8 sided tin, lots of 6 sided. Embossed lettering reads: Evenslice Pie Pan; Patent Applied For.
