This one's killing me. Looked forever to find one this good I could afford. Overall condition is excellent for an old threadless; there is a 2" base flake that ranges from shallow to about 1/4" tall; several areas of very tiny nibbling on the edges of the base; a few annealing cracks from manufacture, plus some mild glass sickness from years of dirt contact; and a fleabite or two. This one isn't whacked like most of them seem to be. It has numerous bubbles throughout, plus some micro fizz as well. Displays gorgeously! Color is a lovely light blue. Mint book is 500-600, my price is $400 including postage to the lower 48.
