Regarding authenticity I can only suggest you research to see if these are known examples. When printed I'm sure low quality paper would have been used as they weren't designed to be long lasting items. If in hand then old paper usually has a distinct musty smell about it and can be quite brittle. Also if there are any printers details to be found then this can also be researched.

Have turned a few upright to save members necks! Regards, Mark.
