The doll house window was damaged. I removed the plastic sheet and the valance.
I had a decal made of the famous B&B stain glass and was able to adhere it to a piece of clear plastic. (This came from toy packaging). Once the stain glass was secure on the plastic sheet, I glued it back into the window frame.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
