A friend of mine recently made some daybills as a giveaway with ant shirt he made, fully licences for WOLF CREEK, the paper stock was actually difficult to get and it is still not spot on. And this was to look like an 80s daybill, to make repro hand litho daybills and get them to look legit would not be easy, or not as easy as going to kinkos at least.
Only real info from the above is don't buy a wolf creek daybill and think it's from a theatre, though they are probably "rarer" than if there really was such a poster.
There was years back a bloke who did colour laser copies of daybills, in sections, stuck together and I think sold under glass, or maybe even had some backed. Touching them is a giveaway, but from a photo difficult, ACTUALLY I think he only tried to use them in trades, oh shit I am rambling.
Some were laminated and I kinda like them as they are full sized reproductions of rare daybills, and good for reference if nothing else (though I'd put them on my wall)
