I was given a template or blueprint from a friend whose grandfather did some type of construction work for Disney in the 60's. The paper is about 4 feet wide by 17 feet long. It is marked as "H-3 Hippo" there are different shapes, one of which resembles the head of hippo. The shapes are marked 1-15, I believe. The patterns are hand drawn. There are arrows pointing to where each piece would fit to the next. Can anyone give me any information on where I could have this looked at to tell me exactly what this is and if it holds any value? I would appreciate any information you could give me.
