This auction is for an oversized folding vintage Lionel Construction Kit Chart on one side and Sub Assembly Diagrams Keyed to Models on the other side. The construction chart shows all pieces at actual size. It can be used as a guide when building models. The sub assembly shows the various methods of attaching and wiring pieces. The piece does show some wear and tearing along creases, but is very presentable and usable. Please see the photographs for complete details. Happy bidding!
