Mariette Hartley and Arlene Dayton?

One would think, since I live in Los Angeles and work in the movies (albeit at a very low level), I'd have lots of Hollywood photos.  Not really.  The fact is they don't interest me all that much. I only have these two pictures because they were in one of those occasionally purchased envelopes of images that almost always have stuff I wouldn't have bought by themselves.

So, the woman on the left is Mariette Hartley, an actress that those of us of a certain age would recognize right away.  She did a lot of episodic television, the occasional movie, and most prominently, along with James Garner, was a long time pitch woman for Polaroid cameras. 

Look at the bottom of the two pictures and stage lights can be seen.  Clearly from a sound stage, probably from one of her many television appearances.  Going by the hair styles and clothing, I took a quick look at her IMDB page, searching for a possible match from about the late seventies through the eighties, but couldn't find an actual show.  As far as Arlene Dayton, her name is written on the back of the top print, but no one by that name  has an IMDB listing. 

Born in 1940, Hartley is still active.  She's had a recurring role in the Fox series 9-1-1.
