at the seaside

A recent afternoon was spent in the rare book room at Powell's City of Books in Portland, OR. There were many treasures to be found, including this children's classic from 1932––Katy Kruse at the Seaside, by Eleanor Farjean. I am quite enamored by these peculiar little illustrations. Are they hand-colored photographs of dolls? I couldn't find much information after some internet sleuthing––perhaps further proof of this title's rarity.
