Use a classic, monochromatic green color palette, with intricate line art and ornate details around the edges to create a cohesive, elegant feel. The card should feature the association name 'Kunst-Förderverein Papst' in a traditional serif font, along with the slogan 'sinnvoll fördern' in a complementary script font. Include subtle, decorative flourishes and keep the layout refined, with ample white space to balance the detailed design.
