The second image really caught my eye and is very confusing. Are they providing a public service to tell kids going to the carnival to avoid having unprotected sex to avoid pregancy? Or do they mean don't come if you are pregnant? That image looks more like "no breastfeeding."
If you run across a safety graphic, especially ones in other countries, please take a photo and send it to me. I'll post your image and give you full credit. Send the images to: SafetyGraphicFun [at] gmail [dot] com.
