Over 100 of America's top musicians have signed an acoustic guitar – a Gibson CJ-165 – that will be raffled off next month in honor of Planned Parenthood, according to Breitbart.

The contest page states that the Old Style Guitar Shop in Los Angeles donated the guitar, which will be raffled in May by the 7 Inches for Planned Parenthood charity group. Its owner Reuben Cox spent five months collecting the celebrity signatures following Donald Trump's election, and apparently represents a "reflection of a group of concerned, like-minded artists at an important crossroad in American history."

In addition to big names like Lady Gaga, Katy Perry, and John Legend, other celebrities whose names make an appearance on the guitar are The Foo Fighters, Michael Stipe (formerly of REM), composer Danny Elfman, Ryan Adams, Henry Rollins, Sam Smith, Nancy Sinatra (yes, that Nancy Sinatra), Mark Ronson, comedian Fred Armisen, Queens of the Stone Age, Charlie Puth, and Gary Clark Jr.

Without the signatures, the Gibson CJ-165 retails for around $1,900. To enter the raffle, Planned Parenthood fans just need to make a donation of $10.  

The 7 Inches for Planned Parenthood drive comes on the heels of President Trump signing of a bill that allows states to defund the abortion conglomerate Planned Parenthood.
