I could not find what appeared in the exhibition and whether it lived up to the stamp images, apart from coming across a car message board photo requesting information on this:
The reply was "Wonderful picture of the Haiyan (Sea swallow or petrel, a little bird), developed in Shanghai in 1958. Yes, as an alternative for the pedicabs. The car was exhibited at the National Exhibition of Industry and Communications in Beijing 1959. There are different sources describing the technical info: 248cc, or 400cc, or 579cc; 1-cylinder or 2-cylinder engine; 12hp; 75km/h or 80 km/h. One source gives the Shanghai Bus Repair Corporation as manufacturer". Not quite a dragon or flying horse but rather cute.
The mainland of Asia is the destination of Sunday Stamps this week.
