@GIFs_22 16 number 4: 9 in the cardboard, 1 in the speed limit, 1 in the house mailbox, 4 in the vehicle license plate, and the one that is in the question statement.
@Airaasayss Are 16 holes: 4 that already have the t-shirt (top, bottom and the arms) and 12 holes in the body of the t-shirt, because each hole that you see, in fact, are 2 holes: 1 in the front and 1 in the back.
