Doug   ....   That patent refers to a card containing 4 individual number cards with the cut perforated tabs which allow the card to be used on several different holders on different types of telephones.    I've attached a picture taken from the patent records of the U.S. Patent Office.

Your welcome Doug.     I stared at the picture you posted for a minute or so before it clicked, because I'd never seen one either.

Doug,

I wonder if that is the back of the card. Did you check what's on the other side?

Haf....I opened it and itís an all black card. Looks as if it was repositioned with the patent date facing out. I love this card. I was selling it on a manual B1 but I will rethink that....Doug
