This is a unique block of four 5c stamps featuring the 1948 Swedish Pioneers, Scott 958, with a first day of issue postmark. The stamps are deep blue in color and have been used, but are in good condition. They were manufactured in the United States and are ungraded and uncertified.

The stamps are a great addition to any stamp collection and can be used to commemorate Swedish pioneers or as a piece of history. As a plate block/multiple, they are a rare find and a must-have for any serious collector.
