"electric" chair

I purchased this chair back in 2004 (see my 2007 blog post discussing it) and moved it home earlier this month. Today I put protective oil on the otherwise untreated wood, and spayed a coating onto the metal and plastic parts. It will be outside until it degrades (unless it has an interested buyer). I now notice the signature and title on the back, but still cannot identify the creator ("Mayday" by Shawn M.).
