We have written about Marceline the Clown and his sad end here. Spanish-speaking fans now have a great new resource from which to learn about him, in the form of this new biography by Victor Casanova, available here. I hope an English translation will be available at some point! Senor Casanova also wants you to know that there is a crowdfunding effort now underway to raise money for a gravemarker for Marceline, whose unmarked grave is in Valhalla, NY. You can learn more about that campaign and donate here.
