"Leave Behinds" - suggestions for divesting?


Marc Auth
 

Hello all, I have a number of these which were left to me. While I have a long-standing interest in aviation history, I am not a serious cover collector. Are these, and quite a few others, of considerable enough interest to put on the "big auction site"; or, could anyone suggest other methods or venues to divest of these.
Thanks for any thoughts.
