Don't know a lot about glass from the last half of the 20th century. This crimped bowl/ashtray seems to date about 1960s I think. Many similar items made by many companies. A particularly nice handblown example with a polished pontil and a color that seems to match Tiffins Wisteria. Although I have not seen this particular example by Tiffin. 4.5 in. dia. 3.0 in. tall.
1860 more in my wheel house, so update me.
