Learn about six different construction vehicles in this guessing-game board book!

Whose Big Rig? features six kinds of specialised rigs used to construct a light-rail system - a tunnel borer, an excavator, a bulldozer, a tie dragon, a tamping machine and a bucket truck-with five different parts of each rig properly labeled.

The answer to each inquiring refrain of Whose rig is this? is revealed under a gatefold, engaging children in an informative guessing game about construction machines and their operators. With lyrical (and factual!) rhyming text byNew York Timesbestselling author Toni Buzzeo, and the expertly stylized art of Ramon Olivera, this sturdily constructed board book is perfect for curious and playful young readers.
