Behind the guy in the white shirt, he's up front/left. Is a stray hand over some kind of a ball. Marble?

When I was a kid many moons ago, I enjoyed comics like "The Katzenjammer Kids", "Terry and the Pirates", "Little Lulu", Li'l Abner", "Steve Canyon", "Dick Tracy", "Captain Marvel, "Plastic Man", etc. (there were a million of 'em) but one never sees these anymore, nor would they understand them, even if they did, as the situations from those times would not be relative to today's high technology and modern lifestyle. My grandfather used to subscribe to a daily Polish newspaper printed in NY called "Nowy Swiat" (The Polish Morning World) which had only one comic strip each day, "Felix the Cat" (in black and white) so until I was a teenager, I assumed Felix was a Polish cat. Coincidentally, at that time (1940's) our Polish parish priest was also named Felix so it all seemed logical to my young, impressionable brain. This is how misinformation gets started and passed along. As for the photo above, it reminds of a line from an old song "Don't get around much anymore" where Sinatra sang "...the funnies weren't funny, they didn't even make me smile..." since none of the kids are smiling.
