This was purchased from an antique mall as you see it, so the attribution of mid-1800's may or may not be accurate. Easy enough to tell by removing the print which you can do while you are replacing a very unattractive back. Seriously, metal adhesive tape???? No self-respecting dealer should have used this method. But it is still a great old print, regardless. 17 1/2" x 21 1/2" framed size. Damage to frame in upper right corner.
