I thought these looked nice. A block of 4, identified as New Zealand Scott 131d (or SG New Zealand Antarctic Expeditions A3).

As always, I fly speck for oddities. The most obvious one is a raised "IA" in the lower right stamp.

There is a very small speck on the upper right corner of the upper right stamp. Just odd.

But more interesting is the broken left shield on the upper left stamp. There is mention of a "feather flaw", but none of these pass that muster. Interesting.
