1974 Zip Code Promotion Plate Block of 4 10c Postage Stamps - MNH, OG - Sc# 1511
This colorful stamp was issued to publicize ZIP Codes. The Zoning Improvement Plan, hence the name ZIP Code, was introduced by the U.S. Post Office Department in 1963. This five-digit national coding system identifies each postal area and allows for speedier and more accurate handling of the mail. The design, which shows different forms of transportation used to carry the mail, was taken from a pop art poster created by artist Randall McDougall.
These are real USPS postage stamps that are accepted by the USA Postal Service as payment for mail posted in the USA however the total rates on the stamps posted must equal or exceed the current appropriate postal mailing rate or extra postage must be paid.
The stamp set shown in the picture is a stock photo and is likely not a picture of the exact stamp set you will receive and it may differ in plate number and/or orientation. However the item you will receive will be similar including having a plate number (if one is present in the photos) and the same number of stamps. Stamps titled as MNH, OG will have no significant creases or unnatural gum disturbances unless otherwise noted.
