Looking for aerial photos of USAF bomber missions over Sofia Bulgaria
 

For a research I am looking for aerial photos from the 1943-44 USAF bomber missions on Sofia, Bulgaria. There are a couple of popular photos in the internet, one with B24s seen over Sofia, but I am looking for other photos. Can you please point me where to ask, some archive or collection? Or even better, if someone of you has? Thanks!
