This image is from a very interesting post at Kuriositas about colour photography in the early 1900’s.
I wonder how long the elegantly boutonniere’d subject had to hold up this hefty volume for this pose. He must have had strong hands. He wears a look of what could be impatience dissolving into annoyance, which may have been staged (serious countenances being de rigueur for formal photographs at the time), or perhaps it was the strain of the pose after all. I tried to make out the title of the book to no avail. Let me know if you can identify it or anything else about this intriguing photograph.
