Here is, in my opinion, the most unimaginative U.S. stamp. It can be found in the Non-Personalizable Postage section (3CVP prefix) of the Scott Specialized catalog. However, the stamp does present a couple of surprises.

Here are the surprises. In the close-up below, the "E" is missing from "POSTAGE".

In this close-up, not only is the "E" missing, but what's left is doubled.

So, yet the stamp is boring in design, it's not in other areas.
Are there any other boring, yet surprising, stamps out there?
