I'm guessing most Americans know by now that the US Postal Service sells “Forever Stamps”; you buy a Forever Stamp at today's first-class one-ounce stamp price, and it will be good for the first ounce of regular first-class postage forever. And instead of a price on the face of the stamp, it says the word “forever.”
Which can result in interesting juxtapositions with the subject matter of the stamp.
Many such juxtapositions can be seen as reasonable declarations of, or hopes for, the longevity of the subject. For example, the Forever Stamp with the word “Freedom” on it seems like a reasonable thing to hope for. And the Forever Stamp with a picture of Dumbledore on it seems like a nice way to declare your interests.
But I recently got a sheet of stamps titled Made in America: Building a Nation, featuring black and white photos honoring America's industrial workers. As Lewis Hine, one of the featured photographers, wrote, “I wanted to show the things that had to be corrected[, and] I wanted to show the things that had to be appreciated.”
And sure, it's great to express an interest in remembering our industrial workers forever. But it nonetheless felt a little weird to me to use a stamp that showed (for example) a millinery apprentice, who I suspect did a lot of hard work for not much pay, with the word “forever” on it.
So I started wondering what more-unfortunate things stamps could show with the word “forever.”
But before I could post asking for suggestions, I came up with an answer that I think will be hard to top:
A 1984 stamp. With the words “If you want a picture of the future, imagine a boot stamping on a human face.” And then the denomination “forever.”
...Still, I welcome other suggestions. And while I'm here, I may as well link to my similarly-themed license-plate-slogan challenge from 1997.
