i had posted a question a week or so ago about a sign id, its been painted over and through the peeling cracking paint it is blue porcelain from the edges in about 6" (thats the best i can see thru the paint over) and i had stated it had stars (like the northstar sign) i got a better look at it earlier this week and i may have misjudged the stars for white dots (like a polka dot pattern) around the edges, like i said its on a pole up in the air, and has an older paint over, I'm sorry to keep beating this dead horse but i thought the dots may present a better clue, talked to the owners again- still no dice SO FAR!!!! also- its a round sign, 5-6' in diameter.
