Classic World 1-2 is an e-Reader level for Super Mario Advance 4: Super Mario Bros. 3. This card was released in Series 1 in Japan. Its official difficulty rating is ★★☆☆☆.

The key art featured Larry Koopa.

Level synopsis
This level is a remake of World 1-2 from the original Super Mario Bros. with several differences: Mario starts the level in the underground area rather than running into a pipe beforehand, almost all of the Brick Blocks on the ground near the exit pipe are now Hard Blocks, the vertical pipe attached to the exit pipe was replaced by more blocks, the Piranha Plant in the goal area's pipe is gone, and all three Warp Pipes in the Warp Zone lead Mario to a room with a treasure chest containing a Fire Flower. Also, as with World 1-1, the Ace Coin replaces the top center coin in the shortened bonus room, and most of the Brick Blocks there also contain coins.
