Help nedeed to find a photograph and the way to purchase it.

Could anyone please help me in telling me how to find and buy a photograph that I find very expressive about the extrem despair of certain people in Vietnam during the vietnam War ? The photographer is MALCOM BROWNE, it was shot in Saigon on june 11, 1963, while he was working for ASSOCIATED PRESS. I haven't find the AP's website yet. The photograph represents a buddist monk who is self immolating by fire, in the middle of the street. The name of the monk is QUANG DUC. Thank youu for those who will help me by transmitting any hints they are aware of.
