Adam:
Good find! I have never seen these before.
The course depicted is much different than today's course because much of it occupied different land. The original routing used a bit of the present course, and a bit of the club's short course, but the other half of the holes ran toward the lake and then back, through what is now a residential neighborhood in Grosse Pointe Farms. The re-routing was done by Hugh Alison who kept his office in Detroit in the mid-20's while working on all of the "Colt and Alison" designs in the upper midwest.
