Watercolor, hand drawn,A close-up of jolly Santa's face, beaming with warmth as he savors a sip from a frosty glass bottle of Coca-Soda, its vintage lettering and condensation-kissed surface prominent. Twinkling eyes, rosy cheeks aglow, set against a softly blurred backdrop of Christmas lights and pine tree branches, evoking nostalgia. Above, retro-style "Merry Christmas" in bold, curved font, amplifying festive charm.
