My colorized version of this Shorpy photo, using GIMP software. I could find no historic references to the original color of the clubhouse, so I guessed by the density of grays that it was probably brown or tan.

This colorization is about 10 hours work. There are so many spokes and horse legs and brakes and leaf springs in some places, I had a hard time figuring out what color to make things or where one thing stopped and other thing started.
