For the convenience of the public, Postal Kiosks (Small-type Post Office) are established at places far way from the regular Post Offices and their Sub-Offices. Mobile Truck Post Offices travel a fixed route each day stopping at various schools, factories, institutions, etc. For stimulating public interest in such new facilities, the Postal Administraction issued a set of stamps using the Mobile Post Office and Postal Kiosk as the designs. The stamps of $500 and $1,800 denominations have a picture of a Mobile Post Office stopping before the main gate of the Executive Yuan in Nanking and those of $1,000 and $1,250 denominations have a picture of a Postal Kiosk functioning beside on entrance to the〝Chung Shan〞Park, Shanghai.
