Back wall of foyer - Donald and Daisy Duck doing yardwork at our place by Don Rosa

Nice art and house - and sounds like you have the most unusual trade story with Mr. Mandel as well!

Yeah, the "Tractor for art" deal is pretty interesting to say the least!  Felix Lu interviewed Dave Mandel on one ofhis podcasts where Dave shows pictures of several of his favorite pieces of comic art from his stupendous collection.  The Simonson Batman vs. Joker cover he received from me is one of the pieces Dave displayed and he tells a fairly accurate version of our deal; I'll share some additional details if you and I ever meet in person!
