Quoted from Venetic:
This is my first TPF, and also i'm also bringing a pin, is there any rules against putting a sign up on your machine indicating that it is for trade/sale with contact info?
Trust me. Advertising your game for sale is welcomed to us collectors. Some of us are looking for projects or additions to our collection. As an exhibitor you will receive a card to place on your machine to let others know if it is for sale.
