Pirate Shark Treasure Cartoon QR Code for Posters

About this design

A treasure chest spilling gold coins sits on a sandy seabed, ringed by orange shells, red coral and pale cartoon sharks with round dark eyes. Square wooden frames and the chest's boxy latch plates disguise the finder squares, while the shark fins, coins and scattered pebbles carry the modules. Dark navy fins and brown timber sit against bright turquoise water, so the pattern keeps strong contrast. A pirate ship mast rises behind the sharks, adding a small storybook detail.
