This surfaced recently on YouTube: photographs of Ontario’s All States Picnic from 1948 done for Life magazine by Allan Grant and turned into a video montage by Gary Cliser. The video lasts six minutes, and there’s some neat stuff. The pictures can be seen individually on this blog.
According to Wikipedia, “The All-States Picnic, an Independence Day celebration, began in 1939 to recognize the varied origins of the city’s residents. Picnic tables lined the median of Euclid Avenue from Hawthorne to E Street, with signs for each of the country’s 48 states. The picnic was suspended during World War II, but when it resumed in 1948, it attracted 120,000 people. A 1941 Ripley’s Believe It or Not! cartoon listed Ontario’s picnic table as the “world’s longest.” As native Californians came to outnumber the out-of-state-born, the celebration waned in popularity until it was discontinued in 1981. It was revived in 1991 as a celebration of civic pride.”
