davidcyclebackThe original was on newspaper-like stock and was black and white (though could later be hand colored if someone wished). I haven't seen your particular item before, but it would seem to be a later reprint. Synthentic plastics is a Post 19th century thing.
The originals of this print are not expensive (no King Kelly, no Billy Sunday), so it would seem the financial value of your find would be directly based on how nice you think would look on your wall.
A good test when you come actross 'Victorian era' sport or non-sport print or poster like this in an antique store or garage sale is to examine the colored areas with a strong magnifying glass. If the colors are made up of a fine multi-color pattern of dots like on a modern magazine color picture or trading card, it's almost certain to be a modern reprint.
