The zip file - GET IT HERE - 145 K has three folders, each containing.
One folder contains a plain B-24D skin (olive drab, no tail art - a slight mod from the supplied EAW B-24 which has the letter "H" on the tail).
The second has the B-24D with the "Jolly Rogers" tail art used by the 90th BG after July 1943.
The third folder is "B -24 Side art" and has a number of side art skins for the B-24, including new ones for Charles H. Cook's plane) and "Big Chief" (another plane from the 321st squadron).
EAW randomly selects side art from this file to apply to the B-24 skin (default or modified). If you set up a formation of B-24's and cycle through them (F9), you will see that about half of the planes have one of the side art panels from this file (the others are blank, and art is placed only on the left nose of the aircraft).

Comments: Lt. Charles H. Cook flew a B-24D named "Cookie" with the 90th Bombardment Group in the southwest Pacific in 1942-1943. At that time, Allied forces were greatly outnumbered, and Japanese invasion of New Guinea and Australia was a very real threat. Bruce Irving has interviewed Charlie Cook and composed this valuable record of his aviation career. The entire article is also available for free download here - Charles H. Cook.
