My very first job as a resident of San Diego was the sign painter at Belmont Park. The side of my shop opened up so I could look out over Mission Beach. I got to paint 4'x8' murals/cartoons throughout the park, I used to pick up comic books at the 7-11 on Mission Blvd and use them as models.........Fantastic 4, Silver Surfer and others all came to be life size on sheets of plywood around the bases of the rides.
You did not do all that stuff in one day, I call shenanigans on that post Steve
