The photo shows a large crowd of men, women and children gathered on a rocky river bank. It's a large outdoor picnic celebration. There is a small 'x' above a man holding two children in his arms. This could be Harold and Jean. Note the how well everyone is dressed. Also note that there is a woman in a canoe in the background. See also 1922.214.171.124.
