YUP put down a few 1000 of them babies about the same time. Worked at the Monument (Gravestone) Co in North Little Rock one summer when I was about 12 or so in the Finish Dept. with My Brother doing the Lettering and Artwork on the stones and traced a can Logo to make an ashtray out of a 6” x 6” x2” scrap chunk of Georgia Grey Stone.
One end of the place had flatbed rail cars come in with 2 slabs of stone per car- as long as the car and 20’tall x 4’ thick. It got cut with a wire & silicone abrasive slurry into several slabs then polished for 6-8 days to get that Glossy Finish You see on the Markers, cut into whatever size was needed for the order and came to Us for the Silica Blasting for the Names, Dates and Artwork (Flowers and such)
Not sure what ever happened to that ashtray but it was a 1 of a kind. Fished & Camped our way back to Houston to drop Me back off to go back to school;(
Life was much more simple back then...
