Excellent condition book.  #539 of 3000.  1st edition printing of 1976.  Signed by George & Stephen Ortloff.  Forwarded by Jim McKay.  Only blemish is a torn front section missing from dust jacket and a small black scuff mark on back cover (both pictured). Otherwise it’s outstanding as pages and binding including edges are in perfect shape.  Pictures provided are of actual book being sold.  Will ship with care so you will receive it as advertised.
