Here's a sheet of interesting Kaiju cards I found recently on flickr.
Found these at this Menko site.
"These are Patchi Kaiju cards from the 70's. The company basicaly took pics of existing Kaiju and collaged them into different monsters in order to avoid licensing." - image and quote source.
The above are Kaiju Menko cards from the 60's.
More found here.
I'll be doing Kaiju week probably in January or February but until then, here's a related link with some really insane toys.
