Charles little sticker says EIN 030 but I don't know if that is correct. I see a little #1 between the P and period after P.Don't see any such listing. There may also be something after the G unless there are side by side periods embossed there. As for the rest of the insulator it is a beauty shade of gray. Has some cool swirling deep draw lines on front and right front side of dome. Also has many various sized bubbles in the glass. Most of which are on right side of insulator. So when you display right side you see all the bubbles and the deep circling, swirling straw lines on the dome. Took my pic on overcast day. Color seems to have blended into white back ground which seems to have absorbed the gray from our east coast overcast.

First email will have maybe one of kind cool insulator shipped to desired address once a one time payment of $40.00 is made (only $32.50 if purchased with two other insulators). Add $7.50 USD's if you have Canadian mailing address. I accept Pay Pal non-fee, personal and money order checks as payment. Will combine shipping and give discount on all other insulators purchased in same order. Be sure to email me an dmake your claim on this piece if you really want. Otherwise you stand the chance of another collector make a claim before yourself.
