This is a decoration designed to be used on your Disney Cruise Line cabin door. This version does not have the sailor cap. (See my other models for that variant.)
The model has an opening on the back into which you can glue a magnet. To ensure Mickey doesn't fall off the door when it's opened and closed, I used a very strong 27 lb rare earth magnet, removing the hook from magnets I already had on hand for cruising. You can find the exact magnets I used on Amazon here: https://www.amazon.com/gp/product/B0787Q54M1
