The big mistake was the newspaper that thought, "Hey, of all the pictures I could take of the park and plaster on the front page of my newspaper... I think the best one is of the severed heads." They of all people should have known better. In this light it wasn't really the park's fault.
This debate reminds me of the annual discussion of whether to use a hanging man prop. For my haunt, thought that it would be easier to just avoid things that would obviously offend some groups. But that is...
I have made a 4' x 8' sign that I will be hanging outside and was hoping for advice on weather proofing.... Glue or Spar Urethane?
-Sign is made out of Foam and Wood with many coats of Acrylic Paint.
-I have used scrap pieces for testing and have found both seem to go over the Acrylic paint just fine. The glue was very slight watered down to spread more easily and the Urethane went on very thin and would require many coats to match the glues...
