Before now, I've not paid much attention to metered covers. But because of a current research/collecting interest, the following caught my eye:


How common were patriotic meter slogans like this? I've been looking, and don't see many, certainly not compared to patriotic covers per se. I presume this would be because meters were mostly used for commercial postage, and metered slogans were more likely to be business related. Even in this case, the slogan is business related.
If you know of others, I'd be interested to know about them.
