Vintage classroom poster that sparks mild fear

In early September, I wrote about the 1944 book "Decorations for the Schoolroom," which gives teachers ideas for posters to put on their classroom walls and art projects for students. There are a few pages devoted to Halloween season, with witches on brooms, cats, bats and owls. Standard Halloween fare.

And then there's page shown above. It's a poster that informs schoolchildren that they should neither run nor perform strange dance moves in front of trucks that are barreling down the road. Because this could lead to death and subsequently turning into a ghost. So, yeah, it's a warning. Or an instructional sheet for Casper-wannabes. Either way, it would be a disturbing thing for child to see on the walls of their cheery classroom. I guess it's a progenitor of the "scare 'em into behaving" public service posters and educational films that especially thrived from the 1960s through 1980s. 

Meanwhile, there's another unintentionally terrifying page in "Decorations for the Schoolroom" that's perfect for Mild Fear. Take a look at June! Don't go near the standpipe, kiddos!
