Offering up these two full size, glass reproductions of the CD 257 'Mickey Mouse' insulator. These were produced in 1983 by John and Carol McDougald in celebration of the 10th anniversary of the National Insulator Association. Both are embossed on the base NATIONAL INSULATOR ASSOCIATION 10TH ANNIVERSARY 1983. No threads in the pinhole. The left one is white milkglass and the right one is 7-up green. Again, full size glass reproductions. Mint condition. I have base photos - please ask to see if needed. Asking $25 each plus actual postage. $45 for both if you buy both. First email gets each. Thanks for looking.
