In blue ball point: 

"To Wikipedia - Dutch Van Kirk Navigator - Enola Gay Hiroshima - 6 Aug 1945"

The signature is on copy of an 8"x10" photograph provided by Dutch, which appears to have been taken by an Associated Press photographer. Therefore only the signature has been scanned and uploaded. Appearance of the portions of the photograph are incidental.
