This is an Antigua 1962 ERROR Cover, sent to New Jersey on 8/9/1962.  

What makes this guy so interesting and RARE is the SECOND IMPRESSION that's UNINKED and Sideways of 3 Pence Postage, situated directly below the BLUE INKED 6 Cents Postage.  It also has an SG 121, the 60 Cents stamp added.  This is a VERY RARE Item for a Specialist!

This Item is over $100 USD so I will be shipping it with Priority Mail in the states, and Registered Mail overseas.  This is to ensure that it reaches you in a safe and timely manner!
