Abstract: An educational and recreational toy particularly for young children is provided for associating common subjects or shapes with related fragrances. The toy includes a series of uniquely shaped game pieces bearing familiar pictorial subject matter for seated reception within complementary-shaped recesses in a game board. Removal of a game piece from its associated board recess exposes a fragrance sticker adhered to the board and having a chemically coated front surface which, when lightly scratched, emits a familiar fragrance correlated with the shape and/or pictorial subject matter of the removed piece.
