Whitefriars ? Crystal Flint Bark Bowl Ashtray Mid Century Art Ice 5.25inx 2.25in

Whitefriars ? Crystal Flint Bark Bowl Ashtray Mid Century Art Ice 5.25inx 2.25in Very good condition. Small production flaw can be seen on bottom. 5..25 W x 2.25 T x .5" thick. Did a lot of research and it sure looks like Whitefriars work by Geoffrey Baxter. I can't be sure because it is not marked. My understanding is that they had Paper Labels and these were many times lost. Heavy, quality piece either way. If I new for sure it would be a much higher price.
