"[One] of the more interesting items that have cropped up in my office this week . . . If you've seen Yonezu's other board books you'll know what to expect. Good thick lines and bright colors. This one has loads of cut outs as well. Plus it's hard to resist the back of the book." Elizabeth Bird, blogs.slj.com "An engaging, visually appealing introduction to basic shapes, developmentally appropriate for infants and toddlers." Kirkus Reviews "Big fun. Both clever and beautiful, this board book uses die-cut holes, bright colors, and clean, sophisticated graphic design to help toddlers identify all the circles around them." Maria Russo, NYTimes.com
