Homemade Mail Box Costume

My 11 year old son and I made this together on a Saturday afternoon (and evening, and a few hours on Sunday and .... lol) Fairly ez to make, a cardboard box, duct tape, bullnosed drywall cornerbead and a few trips to the Home Depot for some finishing touches. We took pictures of the labels and stickers on a mail box and printed them. We had some materials in stock... I'm guessing the total cost to be under $40.00 ;-)
