A companion product, Kotavachrome, was offered in sheet form to make prints. It also came in rolls. Kotavachrome was the Kodachrome product coated on a white plastic base which gave the customer the possibility of having prints made from their slides. It had a very distinct appearance being on white plastic and having the Kodachrome relief image on the surface. It was glossy with an attitude.
Kotavachrome was never sold outside of Kodak, but many of the empty boxes were recycled inside the plant for other purposes and I have seen them sitting around on shelves being used for storage. I had one and seem to have thrown it out, and now only have a Kodachrome 5x7 box in my collection.
