This is a vintage clear glass Armstrong DP1 Insulator that stands 4" tall. It has a smooth round top that flares out around the edges like a mushroom. It has a 3.5" wide smooth base.
Around the bottom of the insulator it reads Armstong's DP1 and on the opposite side it reads Made In U.S.A. followed by what appears to be an A in a circle then 33 52 then three dots.
There is a flea bite on the middle tier. This insulator is still very clear and shows very little discoloration.
