I would say I am an idiot ... but ...
The 12c stamp in my picture came with a group of about 40 Charleston stamps, so I was more interested in the perfs than anything else.
But I was just sorting a general pile from a completely different source, and found *another* 12c WV ... slightly better centered and more legible.
It says HUNTINGTON, as does this one.

Oy vay.

Still curious as to why it's so short, though.
