Apparently the coloring of the sun in the background, and the heavy paper it's printed on, seem to suggest that it is an original, though I've not gotten absolute certainty confirmation on this as of yet. I'm sure anyone who knows this type of collectible can possibly tell from my pics on this listing. This one is in good shape, but Of poster some slight yellowing. Also there are two very small tack holes on the far upper left and far upper right corners of the poster.
