Black and White - Wanted postcards

 I am collecting postcards themed black and white. 

So far, I have these postcards - animals in black and white like panda, zebra, penguin, Malayan tapir, orca; black and white photograph and drawing; chess set. 

Other black and white that I am looking for piano keys; waiter or tuxedo in black and white; yin-yang; Chinese ink painting, Black and White scotch whisky, BW Television and movie, etc. 

If you have an interesting postcard themed black and white, please send to or swap with me. Thanks.
