I had much fun with this creation!! I am not sure if it is an Emu or an Ostrich egg, but it has no cracks and just the opening at the top/bottom however you choose to display it!! Perhaps Horton hatched it!! Just kidding!! The concept started with a hit song by the Synth-Pop group from Norway, aha (MAHA.......rosbawnya fujiyumie askie taskie what you doie).....oops I got sidetracked!! Their hit song "Take On Me, Take Me On"!! Well that EGGED ME ON to create this painting!! And what better title than "Egg Muon" to make it more fun!! By the way a muon is a cousin to the electron although a bit LAHGER, and more unstable too (forgive me Jeffrey!!)!! It is approx. 7" tall X 18.5" in circumference!! A simple cardboard base will be included to display it on!! NOTE: Quoted shipping charges are based on the farthest zone from me, so if you live in closer proximity to Greensboro, NC, the cost will go down!! I refund overcharges less a small packing & handling fee, so even if you pay the quoted charge you will not be overcharged!! BUT PLEASE WAIT FOR INVOICING to maximize your potential refund as eBay now charges a final value fee on the shipping too! Please see my many other art and collectible listings and email me with any questions!!
