Antique Fred Millar Lady Hamilton Engraving Hand Colored Signed Print Geo Romney

This is an antique hand-colored engraving print after George Romney's Lady Hamilton, executed by famous British engraver Fred Millar. There are a few bits of backing that have made their way inside the front of the frame as it has become very brittle, and the backing has a hole in it that does not affect the print itself. Besides those minor issues the print is in great shape. At the bottom is written "No. 152 Engraved and printed in color in one printing." Fred Millar's signature is afterwards. On the bottom left of the print next to the dog is printed "Fred Millar SC, 1910".
It has writing on the back by the previous owner. Among other things, it states that it is 75 years old, but does not state the year it was written. It also says they were always told it was a valuable print but aren't sure if that's true or not.
Measures approximately 14'' wide and 18'' long.
US shipping only (Excluding Alaska, Hawaii, and US territories).
