I spotted this real nice Eddy mask on a Belgian flea market type of site...the guy got it early 80's as a gift from Iron Maiden...Contacted him and he's asking 250 Euro, pretty expensive but I guess it's a pretty rare thing and very appealing to Maiden fans... Check the old pics were his mask is handed over by Maiden !!
