Here are two excellent old black and white real photo post cards with the caption Great Wall, near Nankou. The photos of the Great Wall of China are different but the caption is the same. The photos are clear and detailed. The corners are lightly worn. The divided back is generally clean with some smudging. They are unposted. The publisher listed is M. Hartung, Peking, China. The cards are likely ca. 1920’s or earlier. Buyer will pay $3.30 for all shipping c...osts to anywhere in the United States. Canadian postage is $2.10 and European rates will vary with distance. Email for additional details or pictures. Paypal is an acceptable payment option as is Interac. Always happy to combine shipping costs so please check out my other auctions and good luck.
