I am an Early Intervention therapist for children birth-age 3. Every time I buy new books to use with my kiddos, I find myself always choosing books by Roger Priddy. I love (as do my children and those I work with) the REAL pictures rather than drawings and the solid backgrounds. It's very clear what vocabulary I am trying to teach. Again - I LOVE this book, and all of the others I have in my collection. I return to them again and again.
