Skilled hands engraving
Can't you just hear the customer say "...and while you're at it, could you engrave a message on the inside cover?"
What talent that's shown in this hand graving back in the day. To hand engrave a message in cursive calligraphy where most letters are made up of separate strokes that generally measure 1 to 1.5 mm on average was a pleasure to see.
I just wanted to share with the forum.
