Old Louis Icarte - original?

G'morning!
I found this Louis Icarte print in a thrift store yesterday & am hoping I can get some info on it?
Could this be an original? It measures the same (14" x 20"), so I'm hopeful.
But it's also in rough condition- very dark + what looks like mold in the top left corner of the print Or discoloration, maybe from condensation water touching the paper?
Could it be on the glass & taking it out and cleaning glass would help stains - or darkness in general?
I only paid $20 for it (+ $20 for a 1984 Los Angeles Olympics poster of a running man that reminds me of the early Apple computer / George Orwell commercial that I think first came out on a Super Bowl commercial), so I'm pretty sure I won't lose money - but I'd rather make money!
As always, thank you guys for any help!

Does yours have the Copyright info on it like this one?

 

Looks like some of it is browning caused from acidic burn to me, due to poor quality materials used for mounting/backing.

 

Is that top left? I'll check - thank you!

 

I thought that may be what made it so dark - so I guess it's best to take out of frame - and I'll see spots / marks in top left area are (& see if there's a copyright!)
Thanks
