Introduction to letters of the English alphabet for toddlers. Each page presents one or two of the letters from A to Z. Along with each letter is a word beginning with it. The object referred to by the word appears in a coloured drawing. When a half-page flap is lifted, it is revealed that the drawn object also forms part of a drawing of another object with the same initial letter (and its word also appears). Local author created the Double Delight concept. Harlin is the pseudonym of Australian illustrators Wayne Harris and Donna Rawlins. Also available is 'Double Delight Numbers.
