what's your sign?

I'm confused.
The first sign is located on the window of Chows hardware store around the corner from my house. Not only is terribly specific, not 45 but 48 minutes, it has been up for 4 days.
The other was posted at Brickwork's farmer's market. I'm thinking given the dangerous circumstance that warrant this signage, perhaps a once over for spelling might have been suggested - just a thought.
