It appears evident that American Lithographic selected their last sheet of 350 series subjects for expansion into the 460 series. The timeline for this was during the SOVEREIGN
print run of this sheet (66 subjects) in which the SOVEREIGN 350 backs were printed using a lighter colored apple-green
* ink. More info on this will be presented my next post.
Illustrated here is a page from the phantom "
350/460" Series in my SOVEREIGN set....................
