That hanging Phillips porcelain round looks pretty early, never seen that one before but I don't look at Phillips items too often. Would that be a 42" sign? I wonder what the color combination was? I would like to see a pic of anyone has one in their collection to share.
I believe that it is a 30" inch sign may have made them in 42" as well; here is a pic of the color combo.
Buying: Polarine / Red Crown Gasoline Globes and Signs, Early Chevrolet & United Motors Signs, and 1910's through 1940's Gas & Oil Signs.
