Stack, tumble, and nest and learn your ABC’s as you do! There are ten graduated 5-sided blocks, each with different letters – 26 in all - and the numbers 1-10. Charmingly illustrated by Saxton Freeman, the paper-over-cardboard blocks are printed with non-toxic soy-based ink and build into a tower, 3 feet tall. By Eeboo for ages 2-4 yrs.
