Ever wonder why the ice cream sundae is spelled with a dae instead of a day? You'll find the answer to that and dozens more pop-culture trivia questions, all featured with nostalgic photos and illustrations. Soda Fountain Wisdom is one of a two-book series titled Retro Moments. These titles recall the days when Mom and Dad were teens. Old-fashioned photos and illustrations on every page appear with pithy quotations and comical quips drawn mainly from mid-twentieth-century writers-or with brief, entertaining one-page essays that give historical background to many aspects of twentieth-century pop culture. Retro Moments make great gift books, but bookstore gift-buyers probably will take home extra copies for themselves. These delightful little books carry their readers back to the days of drive-ins, roadside diners, fin-tailed convertibles, and the bright magazine advertisements of yesteryear.
