ca 1925 Mile High Motorcycle Club House Sign with Bike Bikers RPPC Colorado

Description

This is for a ca 1925 RPPC (Real Photo Postcard) with a photo of some of the Mile High Motorcycle Club standing beneath a sign which reads "Mile High Motorcycle Club House" (with no club house visible) which was in Denver, Colorado.  This shows some of the members along with having part of a motorcycle visible at some place in Colorado, but I'm unsure on where they are at. I'm also unsure on the maker of the motorcycle here, but possibly Harley Davidson? This has edge wear and general wear overall. There is an area where there is a thin white line like a scratch, but that area is smooth to the touch.  You can see this in the pictures. The pictures were done with a scanner to show detail of the condition, but these pictures appear more yellow than the card actually looks like when looking at it.  This is from the photo collection of a family member of ours (great grandmother) who was a member of the MHMC in the 20s and early 30s.
