From what I have been told they (any known copies)are on card stock as is the roberts from the catalog, according to my source. The individual i immediately sent photos too stated he believes they are authentic. this individual is in my opinion the most knowledgable individual on odd vintage sports cards in the world. I trust his opinion absolutely, as would most who know him. To be honest when i first saw pics my gut said no good but i wasn't positive. my friend has me convinced the other way now and after having seen them i believe they are vintage as well.
