Décalcomanie murale pour expresso

I live in an apartment built in the 1950’s. These are so cute! I put them up without reading the instructions because I didn’t realize they were in the box but I’m assuming they would be easy to put up if you read the instructions.

Like the finished look, however, I there was no "application squeegee" with the order. Also, the instruction sheet adhered to the back of the invoice and I didn't find it until I had finished applying the decals. All's well that ends well--it looks great!
