Art work...and you do not have to spend much
Start looking really, really hard for old hunting and outdoor magazines. Find one that has gorgeous art on the cover and signed by the artist. Take the cover and have it framed for hanging in his den. If he loves pheasant hunting, for example, find a neat, neat pheasant picture. If you find a magazine from say the 1950s that retro part adds to the interest. Or if you do not like my specific idea use the art idea as a springboard to some other print or art work. It will be very unique in many ways. I bet he would love it and you would not have to spend much money.
