Some or all of the photos may be real, some may be fakes or look-alikes.
The entire plot of Smarty is her trying to get this across to her husbands, albeit unsuccessfully more often than not.
She did some nude shots in the late 40's for the money.
I wonder if Stewart was even aware of this version.
Thanks for the link at Amazon.
This is definitely a movie that I will be adding to my favorites list.
