Astro Rainbow Society of the Deaf
Houston Chapter
also, Astro Rainbow Alliance of the Deaf

A stable organization that does not get much attention, it's part of a national organization
and the Houston chapter began in 1979. It still lasts today, see its Facebook Group

I would welcome additional clippings and info.
