I wonder what the explanation is for the missing Mobil Pegasus logo?
I have a suggestion for that one.
It does look like there was a space for it on the can. But the lettering is in blue, and a bright red was always the colour of the Pegasus logo, IIRC.
However, red has always been the the most fade-prone colour, in dye-based inks that don't contain solid pigment particles. And the printing is done with ink, rather than paint.
