I'm not exactly sure where this photo came from. I think it is from a catalogue for Vespa accessories made by the company Vigano. From the scooter, I'm guessing this was done around 1967-68. You know, those Italians have had, and will always have, the same plan for selling anything. Here's how I imagine the ad men's conversation goes...
"Hey Carlo, we have to come up with an ad program for this new product!"
"Ok Mario, here's the plan - find us an amazingly beautiful young model, put her in a very skimpy outfit, and pose her in/on/around the new product. If possible, we should have her pose topless"
"Wow Carlo! That's a great idea, let's do it!"
This seems to have been the ad plan for just about every Italian product I can think of from around 1945 until the present day (last link NSFW). Who am I to argue with success?
