I have a vintage Anchor Hawking milk glass ashtray that has been used as a trinket dish. It is 5 1/2 inches across and 1 1/8 inches tall. If you turn it over it has a ring on the bottom that looks like old glue residue so it may have been attached to something at some point but you can’t see it and it doesn’t affect how it sits (see the last picture). See my other ads for jewelry, artwork, home decor and more.
