Small Bumper Stickers

My sense is that I see fewer bumper stickers these days. This may be a personal delusion or a lack of attention on my part, given in our visually over-stimulating world. But when I do see them, I've noticed they are sometimes a smaller scale than in the past, as if they aren't meant to be read by a person in another car but instead by a person on foot or bike who is closer and moving more slowly.

Here are a couple of examples:




I realize I'm not providing anything for scale comparison, but even the red and white sticker is not a full-size bumper sticker.
