These 'Let's Jam' posters and prints from Ddjvigo are a great addition to your space. To use them, just pick a spot on your wall and hang them up with nails or sticky hooks. Make sure the surface is clean and dry before hanging. As for maintenance, use a soft, dry cloth to gently wipe off any dust. Avoid using harsh chemicals or abrasive materials, as they can damage the prints. Also, keep them out of direct sunlight to prevent fading over time.
