A Ghia design maybe for a AC four-seater?
Ghia is correct, so a point goes to Allemano.
This photo appears in a very well known book about Ghia, and I must have seen it a hundred times without ever clocking that it's a completely unknown car. There's no caption but the era is obviously mid-1970s. I've had the photo waved under Tom Tjaarda's nose and while he agrees it's got all the hallmarks of his penwork, he doesn't remember it at all...
If anyone can help with more info, please do come forward!
