Yamaha East-West Guitar

Here's a one-off guitar from Yamaha. Dating from 1985, this unusual shaped guitar was the grand prize in Yamaha's then-annual East-West competition. (Can anyone remember what that was actually all about?)

I want to call it the "Flying W" but you'll notice that the headstock is shaped like a letter E and the body, more obviously, is a W, so, E-W = East-West.

It's not the most attractive guitar design in the world, is it? And what's the deal with that extra long tremolo arm? You could do yourself a mischief with that.

I wonder if they actually got many entries, and what were the second and third prizes? (Hopefully nothing quite as outlandish).
