For the 27th consecutive year, WhyHunger is holding its Hungerthon to raise funds to fight poverty. To help reach their goal, the organization has acquired a handful of guitars and other memorabilia by many rock legends, which are being auctioned online.

Included in this year's auction are a red Stratocaster signed by Keith Richards (complete with a Rolling Stones box set),a black Strat autographed by Def Leppard and a sunburst Strat signed by Richie Sambora.

But it's not only guitars that are on the block. Proofs of the artwork from the Aerosmith album 'Pump,' a motorcycle customized by Billy Joel and a meet-and-greet with the Who among the other prizes you can win, all while contributing to a worthy cause.

In total, Hungerthon has more than 1,000 items up for auction, not just from the music industry, but also sports, fashion and entertainment. The closing time for the auction depends on the lot, so be sure to note the time or you run the risk of getting shut out of an item you want. You can view the entire catalog here.

Founded in 1975 as World Hunger Year by the late singer-songwriter Harry Chapin, WhyHunger has raised more than $30 million and provided relief to more than 10 million people around the world. For the past two years, they have received the highest possible rating for fiscal management, accountability and transparency.
