Went and printed out the billboard and mounted it on foamboard. Just eyeballing it right now. This is not where it will go (piggies go on the walkway), it will be up on legs, the bottom higher than the rocks in the background.
There is also a giant scrap metal skull and crossbones that will be hung in the top right corner.
Actually you can see the little hole the left "leg" will go into left of the board.
