Escape room signage
This is my suggestion for your outdoor signage. The sign in at the top can be a light box or just a simple painted metal sign. I have made a night version just to see how it would look if it had light. Since on your description you didn't state you wanted contact info on them i just assume that you only wanted to highlight the location to passers by. If you really want to add more info i can try to squeeze them in there. Just let me know what additional info do you need and wich signage do you need it.
