Here is Number Four:
This is the last of the engraved covers. I am guessing that the artwork is representing an Amateur Radio station from circa 1914, when the League was founded.
The rest of the Covers, which I will continue to post over the next few days, are not as nice as these engraved covers. The artwork is simpler and the Covers don't have that "elegant" look to them.
Posting all these brings to mind that in less than four years, it will be the ARRL's 100th anniversary. I'd be willing to lay money on the odds that things are already in the planning phase. I wouldn't be at all surprised to see a certificate offered for "100th Anniversary DXCC", along the lines of DXCC Millennium.
Maybe by then, the sunspots will really get the bands hopping ?!?
