Regarding the 5 x 2.5 x .75 inch stones, are they all "Barber's Gem" stones? Did Escher produce other models in these dimensions? I thought a Escher is only a Barber's Gem if it was a Pike/Escher stone.
The box it came in was a golden yellow and just has the Escher barbershop scene on the top and no name or model type. It has the standard Escher label on the inside top of the box. I can post pics if that would help.
If anyone has any info on it I would appreciate it.
