sepia and new tricks with old timelines

True; it mainly dates Miss Hadow, I guess. Meanwhile, I've been fixing my sense of sepia. Sepia is not an artifact of aging (i.e., discoloration), it is only a style, one of two tones (sepia and selenium) that actually =enhance= the stability of the print. I mistakenly thought it was both, that is, that there was "natural" sepia (due to aging) and artificial sepia (which gave things a certain look as well as a hint of antiquity). That the photos are "faded" is the age indicator (as well as the fashion of the clothing worn by the subjects . . . uh, those who are wearing clothing). That they are sepia points more toward the style question, which still remains: when was "sepia vogue," that is, at what point in the 20th century did sepia tone prints drop out of fashion? I was amazed to learn that the first Poloroid cameras in 1947 produced sepia prints! They developed b&w in 1950, but there was a crisis because the photos faded rapidly and they had to scramble to come up with a new formula. Next up: new tricks with the timeline. It would be really neat to have a sequence of each section of the book with each subsection "date stamped." So then one could see at a glance as Weer jumps from time to time. I mention this because in trying to look up the announcement of the three visitors (actually the two visitors while Bill Baton is with Weer), I saw again as if anew the wonderful nested quality of it: the tale of Tilly told by Smart; the mention of how Weer told the tale to Margaret (and then in his dream Charlie the dog boy came between Weer and Margaret); then mention of how he started to tell the tale to Bill Baton; and then the arrival of Charlie himself . . . summoned by the thought, or so it seems! . . . and Charlie kind of comes between Weer and Bill Baton in the office like he came between Weer and Margaret in the dream. Alden Dennis Weer 2274: frametale 1974: fat Weer goes to Dr. Van Ness 1920: Weer's birthday party, etc. 2274: Hannah and frametale 1953: thin Weer at Dr. Van Ness's office 1974: president Weer at Dr. Van Ness's office 1920: birthday party 2274: elm branches in the fire 1953: Dr. V 2274: exercise regimen; new races 1921: Christmas at grandfather's house 1920: Hannah tales 2274: frametale 1953: mirror test Something like that, for starters. =mantis=

While I don't have an answer to hand, one data point: in the 1939 film THE WIZARD OF OZ, sepia-tone (rather than standard B/W) was used in the Kansas segments to give them a "dated" or antiquated feel, giving me the impression that sepia must have been out of vogue for some time at that point -- by Hollywood standards, that is, so at least a year or two.
