... Have you come across any plain paper makers labels with just a product number ? or original price on them ? maybe with a company name written in pen ?
Yea I have, some with just numbers written in pen, or typed numbers.
I have 2 or 3 pieces with actual prices, and labels intact, but I packed those up a while ago. They are a Barbini lighter set of 3 pieces, and on the labels underneath they were priced at $6 each in pencil. Which was their original price in the 50's. Unfortunately I never got around to take photos of them. Since they were in Mint condition I decided to packed them back up.
I'll see what other labels I have with written numbers on them and I'll post them. Usually they would be gereric paper labels with just "Made in Italy" on them.
