Book contains over 160 copies of depot drawings from our MRHS archives collection. A total of 45 different Missabe depots (DM&N, D&IR and DM&IR) are included. Some depots have only one drawing while several have 10 drawings or more. The depot drawing copies were made from scans of our entire depot original drawing collection. Since many of the original drawings were large D sized drawings (34” x 22”), we have included a CD with all of the drawing scans in the back of the book.
