“Lecture Espagnole” 1754 Print Perfect condition

I don’t know how to tell if it’s an original etching (not an expert) or a copy but the artist did etchings. https://en.wikipedia.org/wiki/Jacques_Firmin_Beauvarlet Here’s one that’s been hand colored https://www.catawiki.com/l/14116267-j-beauvarlet-1731-1797-lecture-espagnole-1754 And one that’s not colored http://www.pierotrincia.it/en/3157/Lecture-Espagnole---Jacques-Firmin-Beauvarlet.html I think someone needs to see it up close and see if it’s an original etching and then if it needs a new acid free mat and or glass to protect it. I did find this different print by the same artist on eBay https://www.ebay.com/itm/Antique-Rare-Museum-Artwork-La-Chasse-by-Jacques-Firmin-Beauvarlet-18th-Century/174566492007?hash=item28a4f94767:g:AEwAAOSwiEFf36Ai And this https://www.ebay.com/itm/Antique-Hand-Colored-Engraving-La-Chasse-by-Jacques-Firmin-Beauvarlet-Listed/153376249723?hash=item23b5efd77b:g:YL0AAOSwepdcY5en And this is probably the uncolored one you found https://www.ebay.com/itm/Jacques-Firmin-BEAUVARLET-Gravure-Eau-Forte-Originale-CARLE-VAN-LOO-1754/264595760666?hash=item3d9b22e61a:g:QkIAAOSwO2hbzznZ

Pieces like this are often reproductions, but still antique by the simple passage of time. It would need to be physically examined under magnification to determine exactly what you have.
