There is a Mint Toy Museum at 26 Seah Street. Entrance fee is S$16 - rather costly to see some old toys but be that as it may (if you're into old toys), might be worth a visit and these are some of the toys on disply, 3 floors of it. The lighting is not conducive to photography and no flash is allowed.
Frankly I didn't white balance (excuses, excuses) but still its worth a look, especially the price tag on some of them.
