Lily Tomlin with Rainbow Streamer - The Incredible Shrinking Woman 1981

In the movie The Incredible Shrinking Woman 1981, rainbow streamers can be seen along the ceiling corners of the children's bedroom.  In this shot Lily Tomlin, plays as Pat Kramer who is starts to shrink to due a misapplied science.

In 1981 the rainbow did not yet have mainstream recognition as the Gay Pride flag. It would be another 15 years before rainbow was dominantly associated with non-heterosexuality in collective consciousness.  Coincidentally Lily Tomlin is an active member of the rainbow community; she was pioneer ahead of her time, leading the way in that polite and providential manner.
