How do you authenticate a broadside
 

I came across this cardboard poster and I know there are a lot of reproductions of this piece. Is there a way to determine an original from a reproduction? Adding to that, I wonder if there were any originals of this piece or are they all reproductions?

I appreciate any help you all can provide.

Fantasy item..

Yes complete fantasy piece

You should be able to just tell by the type of paper or board, this seems to be too light and bright white - so the above members unfortunately have it correct!

Whoever applied those fake markings on the reverse is about as respectable as an autograph forger or card trimmer.

I own several vintage broadsides -- primarily boxing -- and have yet to see one that includes the year. The "1955" on this fantasy piece is a dead giveaway.
