Definitely see differences in the location of the grommets with respect to the lettering as well as the orientation of the arc in Billups between the two...

I’m believing you Randy. Red is the first color to sun fade with time, not blue.


Wanted early tin litho signage.

I haven't heard that about colors before; ie, the red fading first before blue. Any idea why?

Not sure what happens chemically, the red must be less stable to UV light. See it more in decals than the porcelain signs. Not really a surprise when you buy colorants they'll let you know how UV stable it is. I know blue is a good color, we dope our plastics at work slightly blue to compensate for UV.

Car dealer told me the same, red goes first and even tried to sell me a form of insurance on it. Still have the car 11 years later. The red looks good! Jim should have the answer, shouldn't he?!

Generally red pigments are the most vulnerable to fade in sunlight, but there are weak pigments in other colors too. The last few generations of auto paints have been combating the red fade issue much better. Colors now are under a clear layer that protects them. They are putting UV blocking pigments into automotive clear to keep the destructive forces of UV rays from getting inside the paint film and breaking it down.

But in terms of an authentic, older sign, it would be expected that red would fade sooner than blue. Is that correct?

Yes, nearly all the time, but not absolutely always. There were some weak pigments in other colors, especially back in the old days.
