I just found this array of fun things in a travel collection I bought a couple years ago. Everything was in the envelope with the restaurant advertising. The envelope, the card, and business card came from the China Quanjude Group which introduced the roast duck seen in the photo in 1864, during the third year of Tongzhi, Quing Dynasty. There's also a Boarding Card from the China International Travel Service, a small advertising card which lists the Chinese Dyanasties and the items which can be bought at the store, and lastly, two very attractive Chinese characters on beautiful paper. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
