anybody heard of "Green Door Studio" dollhouse plans?

I bought a third-hand (at least!) dollhouse a couple years ago to fix
up and have become curious to find out more about it and how old it
might be. It seems to have been made from plans, rather than a kit.
In the book "Inside the World of Miniatures and Dollhouses" by Rosner
and Beckerman (1980 edition), I finally found a picture that matches
my house: the "Dream Doll House" by Green Door Studio. Green Door
Studio seems to have gone out of business, as I can't find anything
about them on the Web or when I searched this group's archive. I
would like to find out when the company was publishing its plans.
Incidentally, my house is somewhat smaller than 1" scale -- more like
3/4" -- the ceilings are only about 7 1/2" high and the doors 5 1/2".
I hope someone can help me with this "history" question. Thank you!
