La Lotería de San Francisco
Lotería is Mexican bingo played with illustrated cards, and everybody already knows the cast by heart. So the flyer is built from them.
The card is the layout
Every Lotería deck shares the same cast: el gallo, la rosa, el corazón, la sirena. The flyer tiles hand-drawn versions of them around the edge and saves a clean bordered panel in the middle for the details that change: the date, the time, the address and the QR code.
That split is the heart of the design. The illustration tells you what the night is before you read a word, and the panel stays clear enough to guide you there. Next year, the same layout returns with a fresh center.
