Flintridge Riding Club children's horse show, 1958
Supplementary material reads: "Photo Assignment for Thursday April 3 at 2:30 p.m. Note: This is double assignment, each for possible page one, different days. Pls go to Flintridge Riding Club, get shots of gals preparing for annual Flintridge Guild horse show, and also pix of kids preparing for annual children's horse show. These are two separate events. One to be used on Sunday April 20 and the other May 4. If possible, get action in each without duplicating set up. In one, at least, dramatic jumping. Contacts Friday. Thanks, Carter Ludlow".
