Please identify this DSO

I am attaching the image of a postage stamp issued in 1998 by the Pacific island nation of Palau in honor of the Hubble Space Telescope. Can anyone identify the deep sky object or objects shown behind this cutaway view of the HST? Presumably this is an image taken by HST, but I could not find it among the HST images of DSOs in several books of such images.

Attached Image:

I believe it is the Flame Nebula and the Horsehead Nebula region.

Herbert,

I agree, The Flame Nebula , part of the Horse Head Nebula, and a part of the Running Man Nebula...


R,

Thanks for your answers. Of course you're right: it's the flame nebula and surrounding area, which I would have recognized if the horsehead nebula had not been blocked out by the picture of the HST in the foreground.
