The attached was described by seller as costume sketches by Edith Head for the movie "Cinderfella" starring Jerry Lewis. 

Although this is not signed by Edith Head, the sketches and notes seem consistent with other examples available online.  However, perhaps even more intriguing, the notes and "stars" in red pen were attributed to Jerry Lewis.  I have found authentic handwritten notes online which have specific elements that match up well (e.g., "K", "ee", etc.).

I believe this is a working sketch board for costume design for Cinderfella by Edith Head including handwritten notes from Jerry Lewis.  However, since neither signed the item, wondering about "attribution" and authenticity.  POVs appreciated.
