Nice matched set of 4 plate blocks (#27071) of the 1962 Project Mercury 4¢ commemorative stamp (Sc. #1193).
Condition: Mint NH, VF (centering varies slightly). The upper left stamp of the upper right block appears to have a couple of slightly discolored perfs (see scan).
**NOTE**: Shipping charges are discounted when more than one of my items are purchased at the same time. See what else I have to offer!
