3) "Whats Your Problem" pamphlet. 1945. Folded in middle, just the 2 pages. 7" x 4"
4) "Survival Under Atomic Attack" ( my personal favorite), 1950, cover is missing and first few pages are loose ( not attached at spine at all) . rest is pretty solid for its age. 31 pages. 7.75" x 5"
Wonderful pieces of history! Army Life measures approx. 6.75" x 4". The Song Book measures 5.75' by 4.25'.

Please note that many of my items are vintage and/or made using vintage materials. I do my best to list any major issues but some signs of life and love are to be expected and only add to their charm.
