Giuseppe Vasi - Grand Tour / #19 Porta Angelica Etching

Went to an auction on New Years day and came across this Etching. I texted my wife from the auction to find some info. She found "some info" about the man and about this etching. Also some prices of other etchings that have been sold. I got it for a very nice price!!!

It is well Matted and framed. It measures 8" high, by 12" wide.

Im trying to figure out if this is real, a copy, approximate value, etc..
If nothing else, I have a cool looking etching on my wall!

Please email me if you have any information or knowledge about this.
