UPDATE: A great press photo of the experimental Rolligon jeep (More info on the Rolligon from a 2013 post shown below). This just expired on eBay, but I expect it will be relisted. I’ll watch for it. There’s a long article from the June 04, 1955, issue of the Saturday Evening Post here.
“1953 Press Photo Man Driving Albee Rolligon Jeep Like Vehicle. You are bidding on an original press photo of Man Driving Albee Rolligon Jeep Like Vehicle. Photo has a small light crease left edge & waving right side due to too much glue being used to attach the information sheet onto the back of the photo. Photo measures 6 x 10 inches and is dated 3/20/1953.”
================== ==================
Originally published 2013 .. You’ll note the one pictured above seems to be the same as the one in the swamp, based on the hood number.
This jeep was built by the Albee Rolligon Company, which also built an FC version. William Albee, the inventor, has a son who rode on the FC version. You can see a comment from his son at hemmings.
“This is an original press photo. Credit- US Navy and United PressPhoto measures 9.25 x 7.25inches. Photo is dated –1953.”
The above pictures was published on page 165 of the March 23, 1953, issue of Life Magazine. You can view it in Google without the watermark. It’s still pretty dark. There are several issues of the magazine for sale on eBay. There is also a story about the roll-on in the September 1955 Readers Digest, originally published in the Saturday Evening Post (date unknown).
The Unusual Motion web site you gave the link for Dave certainly has some very odd ball’s to see, well worth the time to go through:
