Great Northern was actually the second railroad (after Santa Fe) to receive a new FT locomotive, number 5700, which was delivered in May 1941. There doesn’t seem to be a data card for that locomotive but here is a painting of it by Paul Meyer from a GM poster. Note that it is dated January 2, 1941, several months before delivery.

Great Northern ended up buying 51 A units and 45 B units, which means some of its semi-permanently coupled locomotives had only three units instead of four. GM issued a data card for number 400, which was delivered in December 1943.
This card is signed H.U. Bockewitz and dated January 10, 1944, a month after the locomotive was delivered.
The data card looks dim compared with the poster, but here is Bockewitz’s painting in poster form showing that his original painting was just as bright as Meyer’s; the posters may appear brighter because they used glossy paper. However, there is still a clear difference in style: just as Dedek put more detail in the roadbed and surrounding vegetation than Bockewitz, Bockewitz put in more detail than Meyer.

The 5700 is also slightly different from the later 400 mainly in not having the large number board on the side of the locomotive. I suspect GM put that number board there to again emphasize that the four units were one locomotive, but it really ruined the lines of the units that had it.
This card is signed B. Dedek and appears to be dated November, 1943, a few months before the locomotive was delivered.
A loyal GM customer, Burlington bought 16 four-unit FTs, numbered 100 through 115. Number 100, shown here, was delivered in February 1944.
This card is signed B. Dedek and is dated January 20, 1944, a short time before the locomotive was delivered.
Northern Pacific purchased 11 four-unit FTs, numbered 6000 through 6010. Number 6000, the first one built, was delivered in February 1944.
This postcard uses the same painting but is cropped differently and color tones are slightly different.
GM also issued a postcard-sized data card for the NP 6000 and a few other locomotives. It was not intended to be postally used. Instead, the back reprints the same text and specifications as the data card.
However, GM or NP made a postcard of the NP 6000 using the same painting as the data card. The back is designed to be postally used and has the NP logo just like a postcard of Yellowstone Park or some other NP destination.
