This is a cool pic from approx 1920 showing a bunch of local motorists ready for a spin, some by car other by cicles.
Bike with reg plate 305 is one great one from Pennsylvania, the Reading Standard. Another seen at the far right. In addition there is what seems to be two Excelsiors and the bike behind 305 is of some unknown European brand.

Reading Standard where the first ones to offer sidevalves on their machines whilst still the IOE (inlet over exshaust)valve configuration was the common.
