Wonderland Books, Bethesda, Md., showcased a surprise cameo appearance by actress, comedian, and children's book author Kate McKinnon, who showed off her new tote bag: "You never know who might show at Wonderland! What a fun afternoon when #katemckinnon stopped by to say hi, sign her Millicent Quibb books (the second one is now out!), chat with customers and support us indie bookstore people."
