apparently there was a machine they sold in the 70’s that allowed one to cut into wood to create layers. Craft machines for hobbyists were popular in those days: rock tumblers, plasticizing half-dome machines and etc.

I’ve never seen the wood carving one, but this guy in the neighborhood of McGee’s in Oakland made a pretty good rendering  of the bar from across the street, saw it last week, my first time in this Oakland neighborhood spot.
