Do you live in Amsterdam, or perhaps have a trip there planned? Well, André 3000 desperately needs your help. It seems he’s lost a journal and has posted missing flyers all over the city in hopes of getting it back. The poster might look like a publicity stunt, but a rep for André 3000 confirmed with Stereogum that he’s genuinely trying to recover his journal.

Here’s the poster—feel free to spread the word. If you happen to have any information on its whereabouts, please email missing@myriadofpyramids.com. I can only imagine the sketches (aside from the Mickey-esque Ricky Rattan drawing on the poster) and flute compositions it must contain.
