And here you can access your very own Transformers and dinosaurs photo booth props! Just go to the link and download the pdf file. It's 4.5MB total so you will have nice, clear props.
Print out the props on heavy card or onto regular copy paper and then glue the pages onto cardboard. I found manila folders worked great. Cut out the props carefully (a craft knife works best) and remember the eye holes in the masks. Attach elastic or glue on a wooden rod and off you go!
