Lois Lenski is the author and/or illustrator of over 100 children's titles, great for ages 0-preteen. So far we have only delved into the "Little" (Little Fire Engine, Little Train, Little Airplane) and "Small" (Fireman Small, Policeman Small, Cowboy Small, etc.) titles but there is some stuff for older kids too (Strawberry Girl, On a Summer Day). Lenski was the illustrator for Watty Piper's (a pseudonym for publishing house Platt & Munk) 1930 classic The Little Engine That Could incidentally. Yes the people are all a bit coal for eyes but the drawings are clear and crisp and text is easy for the younge kids to handle...
