Front-center, handsome fellow in the bow tie is Fred Orson Wyman, husband of Clemmie May Edwards.
Young man on his left could be Robert Clark Pickens, married to Fred's niece, Meura May Brill.
Standing, 2nd from right, Merle Russell Wyman, Fred's son.
The neat, draftman's lettering gives the year 1925. My records and Fred's gravestone say he died in 1923.
