These blocks do not have images on them. They come with stickers you can put on. This makes them an even more flexible toy since the pieces do not need to be only for a "rescue center." They work perfectly with the other Mega Bloks First Builder kits i.e. 80-piece basic bag, safari train, etc. Easy for a toddler to grasp and manipulate. Better than Duplo for toddlers since they do not fit together too tightly. This also makes them perfect for 2 1/2 year-old boys who like to "destroy" their creations! BTW - Very durable!
