I phoned/emailed Del Costello in 2014. He sent me pics of his incredible MP donations to MOMA:
Well, if even Escobar moved to poster markets, I guess there is money
Really, he donated to MOMA and then sued them ? As article said, pretty sure he did well and still doing well as, just like MOMA, he presumably has posters under the bed.
Thanks for the story, def. a 100th post story !
