Many people have brought many things to Nintendo's beloved Shigeru Miyamoto to autograph over the years: games, strategy guides, Nintendo consoles, and even Nintendo-branded character merchandise.  Sometimes people present him with something more unique.  In this case there's a guitar for sale on eBay signed by Miyamoto at the September Nintendogs event in New York.

My friend's selling his one-in-the-world guitar we waited 8 hours for Shigeru Miyamoto (of Nintendo fame) to sign when he visited the Nintendo World store last September in NYC. When we finally got to the head of the line, and to his table, instead of just signing the guitar, he played the first couple bars of the original Mario theme! That was fanboydom at its best.

So there you have it: a guitar signed and strummed by Shigeru Miyamoto.  The reserve price is a steep $700, so anyone who buys this guitar would be better off framing it than playing it.
