No they are known to be actual photos. 4 of the 6 have been identified, and when you find the match it's 100% Somehow they took the original photo and used it to create the embossing. That's how I know none of my images are correct, but I feel like they're close enough that I should be able to find a true match.
Three are in this Net54 thread:

Although now that I look at it they changed the bat position on the Pickering, probably because the foreshortening in the photo made it look like he didn't have a bat in the embossing.
