Yea, I wouldn't touch this thing with a hundred foot pole. Again, my opinion.
The border not being a thing on any other legit example (and no evidence of real examples being cut down) is proof enough to me. The way it's being held and almost wavy/flexing is just not how 110 year old cardboard works. If this thing was being soaked by oils for years it would be destroyed, not perfectly varnished like a piece of wood. Getting an opinion from a art gallery is like getting an opinion from a card shop. It's not even close to good enough.

I have never seen a piece of cardstock become bumpy like that. I don't think chemically it's even possible. But I'm not certain. I'd almost bet to the touch its like a piece of vinyl, or leather like I mentioned before.

To prove this is a 110 year old piece and somehow it is the only survivor with a border, and was soaked in oils for decades while surviving that too.

It would need A. Paper samples analyzed by a Lab for the date. Very expensive.

And In my opinion B. (snowman would love this) restored to remove the "oil". To prove the quality is comparable to an original advertisement. Very expensive.

B. is subjective

But both are a waste of money. This is a forgery. If by some miracle it's real I'll eat everything I've said.
