The famous early Glidden Tours were a test of man and machine and the photos shown here of an early tour, courtesy of the Benjamin Ames collection, show us some interesting scenes. The Southern Ontario Region of the HCCA has recently started posting some of over 100 photos from the 1955 and 1958 Glidden Tour reenactments on their blog. In addition to the Glidden photos, they regularly feature period pre-1916 photos, with an excellent example shown at the (bottom) of a 1910 Sellers 35 in Hutchinson, Kansas.
The Horseless Carriage Club Of America is also another great resource for early car enthusiasts, with classified ads, a calender and tech articles. The Horseless Carriage Foundation Automotive Research Library also features access to a huge selection of early periodicals, all of which have been digitized. More Glidden Tour photos can be seen here on The Old Motor.
