Canfield pattern teal green glass cake stand, vintage Anchor Hocking glassware.
I like this one because it's big, but not quite as heavy as some of the Anchor Hocking patterns. Would easily hold a 10" diameter cake, it's about 11 3/4" overall diameter at the rim.
This looks good without scratching or wear, no chips or roughness. The glue attaching the plate to the stand is slightly yellowed, not uncommon on the old Anchor Hocking plates.
