Vermont was the fourteenth state admitted to the Union. The 13-cent Vermont State Flag stamp (Scott 1646) displays the Vermont state coat-of-arms on a blue field as adopted in 1919 as the state flag. This was the third Vermont state flag authorized.
The coat-of-arms bears a green landscape, which graces half of the shield. In the right and left background, the flag includes images of high mountains and a yellow sky. From near the base and reaching nearly to the top of the shield arises a pine tree of the natural color between three erect yellow sheaves and a red cow standing in the field.
A scroll beneath the shield includes the Vermont motto—"Freedom and Unity". Two crossed pine branches of natural color appear between the shield and scroll. A buck's head appears above the shield.
