Knitting Textbook for Master Course - Certified Tokyo Knitting Academy I don't know the details, but I believe this book is from the Showa 30s to 40s (1955-1975). It has been stored at home, and shows signs of wear. There are some markings, as shown in the photos. This is a very old book, so please understand that the condition is not good, with tears, folds, stains, and deterioration. Please only purchase if you accept these conditions. #MyHomeBookstore #MyHomeShowa #UsedBooks #Showa #Retro #Textbook
