I started to collect postcards of giant pandas found in zoos worldwide inside and outside China. The first pandas I saw were in the Washington DC Zoo, in USA. Later, I have seen pandas in the zoos in Hangzhou and Beijing, China.
Here is one of from the famous San Diego Zoo in California, USA. Thanks to Joao of Portugal. San Diego Zoo is currently home to 5 giant pandas - Bai Yun (F), Gao Gao (M), Su Lin (F), Zhen Zhen (F) and Yun Zi (M).
