It's an odd thing more like an easter egg. first as a kid when you first go past the guards and see Zelda don't talk to her instead take a right there will be a photo go into first person and check the photo's out you will notice a short man with a red hat. It bears a striking resemblance to Mario.
==============================
Check to the right and you will find another picture that looks like Luigi and to the way left you can bearly see yoshi
