For sale is a previously-loved vintage Harley Davidson-related The Enthusiast Magazine from January, 1951.  The condition is good in my inexpert opinion.  There is significant wear along the bound edge including color loss to white, a 2-tone quality in the front cover's gray border (bottom and bound side, zoom in on photo1), light creases and dents from handling, light discoloring of back cover left of verbiage.  Overall, an 7.9/10, especially considering it's 75 years old!  It comes in a clear plastic sleeve with thin white board insert.  This appears to be acid-free due to the nicely preserved color of the magazine.
