The blurring and color combination pretty much made me cross eyed when trying to read the upper line. Bottom ones were fine though.
Of course, I've got bad vision, I'm slightly color blind, and I've had a glass of merlot, so take my visual feedback with a grain of salt.
It would be nice to see some college CCW posters that reminded folks that not all college students are 18 year olds. Folks in their 40's go back from time to time.
