Thank you for viewing. The National High School Baseball Championship was the National Old Middle School Baseball Championship until 1947 (29th tournament). ◎ This is a rare collection of menko (card game pieces) featuring human figures representing each regional middle school team, dating back to before 1947 (approximately 80 years ago), along with a menko sheet from the National Old Middle School Baseball Championship. No individual sales. The images are everything. Please examine the images (enlarge them) and purchase only if you understand and agree. 151
