2NE1's Park Bom shared a pre-debut photo of herself!

Park Bom tweeted the above photo on March 26 and wrote, "Today, my sister Soo Ah found a photo while she was cleaning! Keke. Before I debuted, my sister said she had to be the first to receive my autograph.. So the photo we took as a joke and the autograph over it became a meaningful photo to me. It's pretty amazing ^^"

In the polaroid photo that was revealed, we see a young Park Bom with her long black hair looking at her cell phone. She'd also written '"My sister" on the pictures, and even her autograph seems to tell how much she loves her little sister.
