Ok kiddos and friends... here goes the first of the three.
History lesson. Between the 1930's and the early 1970's department stores and other venues actually charged you to use their toilets. All of the stalls had little machines on the doors that look very much like parking meters.... This is dating me a bit but I do recall them as a kid. They even sparked the crass rhyme, "Here I sit, broken hearted. Paid my nickel and only farted."
So, there are two things in this Universal image that pull both of those ideas together.... focus on the center... and then to the right. Be smart!
