Found this the other day looking for something else. Had to laugh and woder if they were Sheffield knives:
Another one from the Denver Public Library Collection pictures, cira 1892.
A man stands with his hands on his hips in front of the entrance to a shop where "The Wild West Knife" is sold in a camp for Buffalo Bill's Wild West Show near Earl's Court in England. Numerous signs hang outside of the shop advertising the knife for $1. A glass case exhibiting some of the knives is on a ledge to the right of the entrance.
