Up for auction from a recent estate sale in Milford Michigan is an October 1916 issue of the magazine titled "Gas Energy", as shown. The magazine measures 6 3/4" by 9 3/4" and has 48 pages plus the covers. The magazine is complete but does have the inside magazine pulled away from covers (see 2nd to last attached photo) and is loose on the inside.  All 48 pages are still originally attached by the two binding staples and inside pages are still near white and in nice shape. Lots of information on engines from that time period along with several pages of advertising.  Shipping will be between cardboard backers for safe delivery. Exact shipping charge based on your address.
