This is a set of stamps I bought about 45 years ago. It says "Sogo's 150th Anniversary Festival." I believe they are stamps themed around Japan's 1970 Expo. They appear to be unused. Please take them if you are interested. I will lower the price according to supply and demand. The following is an explanation from AI. I don't think they are used, but it says they are used. ------------------------------------------------------------------ A set of 5 used stamps from Vatican City themed around famous Japanese landmarks. - Series Name: 15th Commemorative Special Exhibition - Stamp Type: Used stamps - Issuing Country: Vatican City - Design Theme: Famous Japanese landmarks - Number of Stamps: Set of 5 Thank you for looking.
