Interesting US Army booklet entitled "BTF 100-G-3, Bombing Tables, (Fluorescent) for Bomb, Incendiary, 100-lb, M47A1 or AN-M47A2 (NP or IM Filled)," 6 x 8.5, 50 pages, February 16, 1945, interestingly printed with fluorescent ink on black paper so that the tables may be read in the dark by use of ultraviolet light. This was done in order to preserve the pilots' night vision. In fine condition.
