He also appears to have gone by Nobushige for a given name as his Baseball-Reference entry is under that name.
Morishita had a number of menko cards during his career as well as a card in the 1967 Kabaya-Leaf set. I think he only has a couple modern cards from the 2006 BBM Nostalgic Baseball, 2008 BBM Hawks 70th Anniversary and 2012 Epoch JPBA History Of Best Nine sets. Here's the cards I have of him:
|1967 Kabaya-Leaf #314|
|2006 BBM Nostalgic Baseball #050|
|2008 BBM Hawks 70th Anniversary #14|
