This is a postcard set from the Osaka Expo "1970 Japan World Exposition," held from March 14th to September 13th, 1970 (183 days). This is a rare set featuring night views ☆ Contents: ・Seal: 1 ・Postcards: 23 (1 duplicate) The box says "22 views," so it's likely complete. There's one extra duplicate, but I suspect it was just my uncle, the original owner, being whimsical (´ 3｀) There is some age-related soiling, but it's in relatively good condition for a 55-year-old paper collection. I hope someone will appreciate it. I will ship it promptly via post ε=(ノ・∀・)ツ I am a private seller, and this item has been stored at home for a long time. I hope to do business with someone who can understand this ( ゜∀゜)人(゜∀゜ )
