"Create a birthday voucher with the theme 'Clay and Bubbles.' This is for a pottery event where sparkling wine or champagne will also be served. The voucher should therefore depict a nice drink (e.g., a champagne glass, a coupe filled with champagne), flowers, and a pottery piece. Use an illustrative hand-drawn style. The following text should be included on the A6 portrait-format voucher: Voucher for a 'Clay & Bubbles' Event Location: Munich, locations change monthly Date: Events take place monthly"
