Create a finished square Christmas joke card for a class party table, designed to remain clear when printed small on cardstock and viewed at phone-thumbnail size. Use a warm ivory card background with generous safe margins and a cheerful, clean storybook screen-print look: smooth gouache-like color shapes, crisp dark outlines, subtle paper grain, bright flat lighting, and restrained festive red, evergreen, and golden yellow. Keep the palette playful and cohesive, not cluttered; use only a few tiny starbursts as decoration. Set exactly these two lines, with perfect spelling and punctuation, and no other text: first, “What is an elf's favorite kind of photo?”; second, “An elfie!” Preserve the exact wording and casing. The setup is a smaller, highly legible line near the top. The punchline is the largest and boldest element, placed directly below it, with strong contrast and enough breathing room to read instantly. Use chunky rounded sticker-display lettering with wide compact proportions, a rich evergreen face, a crisp cream highlight, and a thick candy-red outer keyline; clean edges, even spacing, no warped or obscured letters. Make the punchline especially prominent while keeping both lines readable at small print size. In a separate lower area, show two friendly little elves leaning together and taking a selfie with one smartphone held at arm's length. Make the phone and the elves' delighted expressions unmistakable; show both elves in the phone's selfie view. Keep the illustration below and clearly apart from the text, with no overlap. Give the elves simple red-and-green outfits and pointed hats, with a few small warm-gold accents. The card should feel lively, sweet, and family-friendly, with the joke—not extra Christmas scenery—as the focus. No borders that crowd the text, no additional words, and no other jokes.
