Take a trip back in time to the prehistoric! The Yellow Door Let's Investigate Dinosaur Footprints are double-sided with the raised footprint of a dinosaur on one side and the image of the dinosaur on the other side. Ignite children's curiosity and imagination whilst they investigate and compare the dinosaurs. Children will love taking wax rubbings, making imprints in modelling clay or sand, then washing them clean again. The footprints are made from a stone mix so are durable
