Lava Flow - Non Flocked Blacklight Poster 24-by-36 Inches This poster features an image of a groovy lamp filled with a peace sign, mushroom with dancers, and a smiley face. The whole poster really gives a lava flow feeling with warped and wavy accents including a checkerboard pattern. The colors are vibrant under normal lighting but also glow under blacklight for that truly psychedelic feeling.
