U.S. Army Divisions in World War II, provides a graphic overview of the formation, expansion, and campaign history of all 91 divisions of the U.S. Army Ground Forces from 1939 to 1945. Every infantry, armored, airborne, mountain and cavalry division is represented. In addition to a high-level overview of the complete mobilization of the U.S. Army, detailed information for each division is mapped including: dates of activation, movement overseas, and entry into combat; commanding generals; casualty and days of combat figures; and more. Detailed maps of each theater show divisional campaign histories and provide a unique perspective of the size and flow of the entire war. This print provides you with all the information you need to understand the scope and flow of the U.S. Army during World War II.
This print is dedicated to the men and women who have served and are serving with the U.S. Army.
This print is printed on high-quality, fine art, acid-free archival paper. It was printed on a Heidelberg offset press. In addition to the four-color printing process, each print is sealed with aqueous-satin coating to provide further longevity.
Below are snapshots of the print at the actual size. Notes: 1) that the print quality of colors and text sharpness are superior to the images below and 2) the colors of the print are slightly different than the colors in the images.
Across the top is a complete overview of the entire U.S. Army divisional force mobilized for World War II. In one sweeping view, you can see information on all 91 divisions including: nickname, type, source, theater deployment, organization, and World War I service.
At the left and below are snapshots of the middle section of the print. This section displays the chronology of each division during the war. For every division the following content is mapped: date of activation, date of deployment overseas, date of combat entry, the length of time training, and the length of time overseas before combat. All commanding generals for each division that served during the war are charted. Also, days of combat, the number of casualties and end-of-war status are provided.
There is a detailed map for each theater of the war showing the campaign history of every division that fought in the theater. This provides both a high-level view of the entire theater plus an indepth view of the campaign chronology for each division. Below is a snapshot of the European Theater.

Marion: Excellent chart on the Divisional units. However it does make one wonder
just whar in hell "days of combat" consisted of in interperterting this phrase. Looking at the chart I see the 3rd Inf. Div had 531 days of combat yet sustained 25,977 battle casualties and the 32nd Inf. had 654 "days of combat" yet only sustained 7,268 battle casualties. Also, the 4th Inf Div sustained 22,660 battle casualties and was not in the
top 10 of "days of combat. Also noticed the 101 A.B. Div was not listed in the casualty
count or the "days of combat" . Kinda makes one wonder about the true meaning of what "days of combat" really is and its true meaning. But gal, these facts sure opened
my eyes in a way.
I contacted the creators today regarding their fine print and hope that I will hear back from them.
I would like to compare the division stats to others. Let's see what we can come up with.
Later that same day...
I heard back from them this afternoon and we have arranged to barter; I will advertise for them and in exchange I will receive the WWII Divisions print, and one other of my choosing. How very nice. I love the barter system. 
Will let everyone know when I receive my prints. I am very excited. This should be a fine addition to my office collection.
Thanks in advance Larry!
