[Machine Translation] *This book is brand new. It is not a used item *This item is a book only. Apparel items are not included. Unlike vintage denim, old sweatshirts are not yet generally recognized. However, many of them, especially those made of cotton that began to be produced in the 1920s, are highly prized by fans for their rarity, and many of them are now sold at prices surpassing those of denim. In this book, with the cooperation of vintage sweatshirt collectors, we have included many rare models that cannot be found on the general market. In particular, prewar models are so rare that there is almost no chance to obtain them in the future. Please enjoy this book as a reference book of sweatshirts, which is said to be the end of the road when you master vintage wear.
