It was actually for my wife’s art project and I was helping to source the 2-way mirror. Here is a pic, doesn’t really do it justice but gets the idea across. It’s about 13" inches tall and 16" wide.
Funny story, this pic actually uses just the film itself for the “glass”. The glass we sourced to apply the film to was from a cheap frame from the local dollar store, and after applying the film and assembling the mirror is all looked great. But then at midnight before the project was due, the film started to cure and exposed this text that was baked into the glass and covered the whole surface. So, the glass was removed, and then the film was cut out and stretched out to function as front reflective pane on its own.
Moral of the story, don’t use dollar store glass for projects, dumpster-dive a glass repair store instead
