This Akro Agate flip is hard to find with its pressed swirly glass pattern on the sides, and what makes it so interesting is that it turned up on the first season, second episode of Mad Men, when Betty invited her friends over. Look at the screenshot below I took from that episode!
It is 4 5/8 inches in diameter by 3 inches high. The lid is very shiny with the usual myriad use marks. I did find it without a knob, and I’ve replaced that with one that goes perfectly with it.
The bowl is very shiny with few if any use marks on rubs on the glass. I see a straw mark or shear line on the bottom. The mold mark is: 4.
