4-color letterpress printed oversized envelopes that were used for sending out mail order catalogs, with additional 4th run crossing out the P.O. Box address and adding a row of ornamental triangles and new street address below. Printed on light brown kraft envelopes from the United Kingdom with stylized “SAVAGE REPUBLIC AIR PACKET POST” inscription and TWA airplane at top left, IPR return address across the upper center of the envelope, and a 35 cent Savage Republic Air Packet Post stamp imprint at lower right. Red star and “Another Independent Project Air Packet” printed on flap. A little over 440 envelopes were printed in May of 1987; this listing is for those overprinted later with a new address (see other listings for Version 1 for those non-overprinted envelopes).
