On the front of the card a simple window frame is drawn in thin black lines, with four panes lightly filled in pale yellow like soft morning light. Sitting on the wide sill is a small cat in monochrome, outlined with minimal strokes and a tiny curved smile that feels like a friendly secret shared with the viewer. Its round eyes look gently outward, giving the scene a calm, affectionate tone that fits close friendship. Next to the cat, a single flower opens with bright yellow petals and a green stem, adding a sweet touch like a quiet gift 🎁. The background stays plain white, keeping all attention on the window, the cat, and the flower. Below the illustration, the words “Happy Birthday to you!” appear centered in slightly uneven black lettering, with the exclamation mark adding a bit of celebration 🎉. The pale yellow panes sit evenly in a two-by-two grid inside the black window outline.
