The Bowling Museum in Texas has an old silent film short from the 1920s called “Pin Action.” At the very beginning, there’s footage of Frank rolling a couple of shots. You might want to contact the Museum to see it.
Your grandfather, Frank, bowled with my grandfather, Baxter Reed Sharp, in the Chicago Classic League. I know their team traveled all over the country to bowling tournaments in the 30’s. Frank helped my grandfather and father build a cabin in Nestor Falls, Ontario after the war. We have some very old and fragile silent movie footage of them during the building phase. I never met Mr Kartheiser, but his name was a part of many conversations in our household. I know my grandfather considered him a good friend.
