(CNN) - A Norman Rockwell painting worth about $1 million has vanished from New York.

Rockwell's 1939 work, "Sport," was featured on the cover of the Saturday Evening Post. The original oil-on-canvas painting was being kept in a New York City storage unit.

However, sometime in September, it disappeared. The work was auctioned off earlier this year for just over $1 million.

The New York Police Department is actively seeking information about where the painting may be.
