Answer: Max Fleischer's children: Ruth and Richard!
Taken about 1918 (& likely on Flag Day), this would have been taken only about
three years after President Wilson first declared July 19th as Flag Day.
Ruth went on to work in Fleischer Studios (she was also a performer and was played a featured role in the Carrie of the Chorus series), and married Head Animator Seymour Kneitel.
Richard went on to become an award-winning film director whose credits include
movie classics such as 20,000 Leagues Under the Sea (1954), The Narrow Margin (1952), Soylent Green (1973), The Vikings (1958), Compulsion (1959), Fantastic Voyage (1966) and The Boston Strangler (1968).
