Hand coloured sea life etching from 1858 in an unusual frame

This pair of English hand-coloured etchings showing various bits of unfriendly sea life have been shown off in all their spiky glory with a folksy hand-carved frame. An instant talking point, this is art to draw attention and add texture to a space. It is a unique piece. 

Dimensions H x W x D in cm 45 x 42 x 3.5

Please note the frame is in good vintage condition, well shown in the photos, but not one for a lover of uniformity.
