Abstract Noah's Ark - Etching

This one was my mother's. All the years she had it, I cannot remember where she had it displayed. I am not sure if it is pen or ink, but I love this piece. There are two signatures in bottom right corner and titled across the bottom. Everything about this works absolutely great together; the frame, red edging, all of it works. I have not seen any other works by this artist and would appreciate any input. Thanks
