What is my numbered (252/5000) On the Prowl print by Al Bertram worth?

Ten years ago I paid 150 each for numbered and signed group of seven prints; all Group of Seven are deceased now but would not expect to get very much more for just a numbered print if not signed of Al Bertram.

It is numbered and signed. His signature and the printed name

I can't give you a figure without seeing it, or having it 'in hand', and we can't do that here, of course, even from a posted picture. Appraisal would depend on condition as well. You will have to have it appraised by an art expert.
