Informative Caption was so Informative AND cheerful for this photo, which is in and of itself a hoot:

“Traffic stoppers are the Supremes, America’s top female vocal group, who opened at the Fairmont Hotel this past weekend. Shown hopping aboard a cable car in front of the Fairmont are (L-R): Florence Ballard, Mary Wilson and Diana Ross. The girls, in their early 20s, have been singing together for just a few years, but have a supreme list of top-selling records, major tv appearances, and one night stands with standing room only. Their hometown is Detroit, but with their great reception here, they’ll obviously leave a bit of their heart in San Francisco, too. Filed: May, 1966.”

Whoever wrote that was definitely pleased with his kicker when he filed his copy. (In actuality, as far I can tell, Ms. Ross didn’t come back to San Francisco until 2011, although Mary Wilson performed in the city often.) But the vibe of this photo is a joy: Three women, in very cute outfits and absolutely perfect accessories, zipping their way down the street in (arguably) America’s most picturesque form of public transportation, looking with joy toward summer. Let’s all take this feeling and run with it!
