3 Framed Wildcat Pictures of Wild Cats, Signed Robert Post?

Framed Wildcat Pictures, Signed These pics could use a good cleaning..(I gave them a wipe down) 3 Framed Pictures that appear to be given as gifts. Each is signed and also signed on the back(1 Pic has damage to the paper on back- see pictures) These are vintage items with marks / dints/ chips out of frames but overall good conditions I do think the signature is Robert Post but you may be more knowledgeable on this. I think they are prints of paintings...but have no idea for sure.. Lion with Lamb, signed: 12" x 10" - Actual picture is 7.5" x 5.25" Lion with Baby cubs: 13.5" x 11.5" - Actual picture is 7.5" x 5.5" Cougar(I think) chasing a rabbit: 12" x 10" - Actual picture is 7" x 5.25" The measurements are approximate.. Please ask any questions before buying. I am happy to send more pictures!
