Not really ads but it's a catalog that I found while searching on google images, it has Monterey bikes too which I have never seen any catalogs or ads for them before which to me seems to be a shame.
Super cool add!
I'm in the process of recieving a 70's muscle bike that my wife's uncle has in the garage. I have only heard about it and never really seen it, but I hope it's cool.
Keep it up
