Hmm...not sure his soon-to-deliver wife would appreciate him "studying" Victoria's Secret catalogs! "No...really honey....it's for the sake of my art!" Just kidding. I think you are right. Catalogs are great sources of this kind of education. You can see many "staging" tricks all in one place. Although many of the poses might be deemed something less than "natural." After all, how many of US would look natural posed in our underwear!
