No indicia in the book. Patoruzu appears on cover only as contents of book being indexed is an otherwise unreleased issue of Fox "Animal Crackers" later released as Leo the Lion (I. W. Publishing; Super Comics) #1. It is likely, therefore, that this was released in the early 1950's though the covers were printed much earlier. Another copy found to contain From Here to Insanity #10 (Charlton, June 1955). A copy also contains Animal Crackers #31 (Fox, July 1950).
