I believe that "vintage white" is a range of various attempts to duplicate an original Fender Olympic White finish that has yellowed with age. Fender didn't originally have an "ivory" or vintage white color, but they did use a yellow stain under the paint - sometimes. :toothy12: And a lacquer over it, that yellowed. They had a "Mary Kay White" that was a translucent color, not a paint.... some people get amazingly obsessive about these things. There are some ivory Les Pauls, as well as white ones, and the whole subject has gotten very jumbled-up.
