This is a really nice Cobalt Blue Moderntone 10 1/2 inch Sandwich Plate made by Hazel Atlas Glass from 1934 to mid-1950s. This Plate is in very good condition with no chips or cracks, however, there are a couple mold lines visible on the plain surface of the plate (common to see in the vintage, plain glass). This can be a hard plate to find. Be sure to search our other Moderntone available. We guarantee items to be as described. THANK YOU.
