Ginga Nagareboshi Gin Songbook. This songbook was made in Japan in 1986 by Nippon Columbia Co. Ltd.
This book has hard cardboard like covers and pages. In the picture you can see the front cover of the book and couple of the pages. All of the pages are very colorful and include lyrics of the songs. It took me years to get this into my collection. I managed to bid this from a Finnish auction site Huuto.net. Definitely one of my favourite items.
The songbook has also its own music cassette. It has two sides with four songs in each. The cassettes total playing time is 30.08 minutes. I hope I can add it into my collection someday.
