Create a finished portrait 3:4 printed sign for a public library’s Letters to Santa station. Make it warm, festive, welcoming, and instantly readable from across a room, with generous home-print-safe margins. Use a soft warm-ivory paper background, a fine evergreen-green inner border, and restrained tiny gold snowflake marks in the corners. Keep the decoration clear of all text. Set only these exact words, with exact spelling, capitalization, and punctuation: headline “Write to Santa Here!”; instruction “Letters go in the mailbox by December 5”; library name “Maple Grove Public Library”. Do not add any other text, lettering, numbers, labels, or signatures. Hierarchy: headline is the largest and most prominent, centered near the top in festive deep-red custom lettering. Build the letterforms as friendly, sturdy, slightly rounded sign-painter serifs with generous counters and clear spacing; add a restrained warm-gold inline and a subtle evergreen offset shadow for crisp separation from the paper. Set the instruction directly below in a clean, highly legible dark-evergreen serif, large enough for easy reading at printed letter size. Place “Maple Grove Public Library” as a smaller but clearly readable centered footer in matching evergreen lettering. The lower middle features one large, charming traditional red postbox, front-facing with a rounded top, dark mail slot, small brass-colored hardware, and a simple blank cream mail flap; place two or three visible cream envelopes tucked into the slot or resting beside the base. Keep every envelope blank, with no writing or symbols. Give the mailbox and envelopes a lightly illustrated, softly shaded, paper-and-gouache finish with clean edges; they are the main visual subject, but must not compete with the headline or obscure the instruction. Add only a few small evergreen sprigs and gold stars around the illustration, leaving the text unobstructed. Warm, even printed-paper lighting, rich Christmas red and evergreen against ivory, polished and cheerful rather than cluttered. Centered vertical layout, balanced spacing, clear separation between text and illustration; no mockup, no photographed room, no extra copy.
