More recent outdoor life magazines, while not as valuable as their older counterparts, can still have some value, especially if they feature articles or covers by well-known sportsmen or conservationists. For example, a copy of Sports Afield magazine featuring an article by Theodore Roosevelt or a cover by the renowned wildlife artist Ray Harm can be worth several hundred dollars.
In general, outdoor life magazines that are in good condition, feature notable content, and have historical significance will be the most valuable. However, the specific value of any given magazine will depend on the specific factors mentioned above, as well as the current market demand.
