Why is "FOREVER" crossed out in the image?

When you see "FOREVER" crossed out, it's just an anti-counterfeiting treatment we added to the official website, brochures or e-commerce display images to prevent others from directly downloading high-definition images and then printing them as fake stamps. We call this practice digital masking; the actual purchased physical Forever Stamp, FOREVER, will not have the streaks on it.

So the lines in your picture:

• It does not mean that the stamp has expired;
• It does not mean that you cannot continue to use it;
• Nor a postmark;
• It's just an artificial anti-copying line added to the display image.

Note: If the physical stamp you receive actually has this crossed line printed on it, be cautious. It may be a display sample, a replica or a fake stamp, rather than a normal usable stamp.
