Just a simple 2 inch or 3 inch circle brand with that logo on it. The original idea was to iron brand the prize boxes with the AFN logo (just as something fun and neat.) I can get them custom made on amazon for under $50, or around $70-100 if I want an electric element added to it (so they don't have to be fired over flames/coals.)
The rubber stamp was significantly cheaper; but I'm waiting on the stamp to show up still and it looks like there are some things to consider when stamping unfinished wood with ink (it can be done for sure!)
