If you are looking for a new guitar and have over $10,000 to spare, you can invest in a Martin D-28 left-handed guitar autographed by Paul McCartney.

Proceeds will go to the Nature Conservancy's African Elephant Initiative, according to “Rolling Stone.” Bidding on Ebay starts at $10,000 but will most likely sell for more.

In addition to McCartney’s signature, he also scrawled, “this guitar saves elephants,” on the instrument. Money raised from the proceeds go to increasing the protection and conservation of elephants. It additionally will reduce the demand for ivory, by working with China to educate members of the private sector to have less demand.
