This is the second Halloween-themed press photo I have of Dorothy Dix, which was taken in 1928.
In this photo Dix is wearing the same daring two-tone silk outfit, and showing off a lot of skin, baring almost every square inch of her lovely arms and legs. Also, once again, Dix, carrying a JOL, has a veil billowing out behind her (the end of which she is standing on). And she has been photographed standing in front of a bare wall casting what is supposed to be an eerie shadow.
The classic 20s spooky Halloween photo is below. The photo on on the left is from flickr, where the model is not identified. The photo on the right is a 2010 MichellexStar homage featuring Sabina Kelley.
In 2010, the model in the original photo was identified as Clara Bow, which is possible, but the photo is quite different from the Clara Bow Halloween photos I have seen elsewhere (gathered here), so I am a little skeptical.
Anyway, as you can see, the shadow play in both Dorothy Dix photos (and in the Colleen Moore photo I posted a few weeks back) is nowhere near as sophisticated as in the Clara Bow(?) photo above, but using shadows like this does seem to have been typical of the period.
