I’ve found a couple of Atlas GP38s in first CP Multimark scheme, with the large multi and narrow stripes on the cab and nose:

However, I have yet to locate any prototype photos showing GP38s in this scheme. While Atlas is good about only doing prototype paint schemes, could they have done a fooby here?
