Marusan's GyakushuGoji sculpt is one of the best; and this 2004 release may be the best to date. This variant looks as if it jumped right off the screen in 1955 - molded in a dark gray/black and sprayed with a light gray (almost white) - giving it that grayscale appearance.  This is similar to the Medicom re-release years later - the biggest differences are a slightly darker vinyl and more prominent spray, notably the stripe down the center of the chest.
 
Godzilla is 9" tall. 
 
Comes with header and bag.
