2 Vintage Corning Glass Coffee Mugs Cups No. 34 No.37 1960s 1970s

60s-70s microwave-safe mug cups marked "Corning USA M-Wave OK" on bottom. The sunshine yellow stripes mug is marked "34", the green flower band mug is marked "37". Both in excellent vintage condition. I read they do not make this type of glass anymore, I guess that is why Corning items are collectible. (I have other vintage Corning pieces lurking around somewhere, maybe I'll post them later. Grandma-ware...) Smoke-free! No stock images - all photos are of the actual items listed.
