some interesting and unusual stuff I found on Progress-is-fine.Blogspot.com
the unusual rims? called "high flotation wheels"
home made cannon... I think it's likely the larger diam breech area is made from a natural gas / acetylene tank
this is one exaggeratedly opulent advertisement!
the Chicago license plate... I've posted one before, it was a way to extort more money from the population so the local city government would get rich. It's unheard of now, but it wasn't always just state plates that were required to use roads
