State Fair (1945)

Farm family, with discontented daughter Margy, head for the Iowa State Fair. On the first day, both Margy and brother Wayne meet attractive new flames; so does father's prize hog, Blue Boy. As the fair proceeds, so do the romances. Must lovers separate when the fair closes?

At 19:13, there is a very brief glimpse of a man rolling 3 hoops over his back, soon followed by another man juggling 3 clubs.
At 20:28, we see the same two jugglers in the background, juggling 3 hoops each in the air briefly, stopping, and then beginning to pass 6 clubs between them.
