This card shows a simple black-outlined window centered on a bright white background, with four panes filled in a soft creamy yellow that feels like warm light. From the lower part of the window, a small white cat peeks up with pointed ears, round dark eyes, a tiny “x” nose, and fine whiskers, giving a shy, affectionate look as if sharing a quiet moment with someone special. One paw reaches forward to offer a single yellow flower with a darker center, turning the scene into a gentle, friendly gesture 🎁. Beneath the illustration, the words “Happy Birthday” sit centered in a casual handwritten look, printed in black for easy contrast. A faint gray shadow under the window adds a little depth, like the frame is resting just above the page. The limited palette of black, white, and yellow keeps the focus on the tender exchange between the little cat and the viewer 🎉. The window’s thick textured lines and the soft yellow panes stand out crisply against the open white space.
