This set of four Dino footprints is just perfect for all kinds of adventure and boy scrapbook layouts. I just love the idea of including these on museum layouts or documenting one of the many dinosaur themed adventures that we have taken including things like Universal Studios, Dino Egg science kits, and even just adorable "roaring face" little kids. These come in a set of four black acrylic pieces that measure approximately 1.5 inches x 1 inch.
