Special thanks to the guys at Import Monsters for acquiring the image. S.H. MonsterArts is tackling Showa territory now! The S.H. MonsterArts Godzilla 1964 was just revealed by Yuji Sakai at Wonderfest! The figure was apparently mean't to be revealed at Toy Fair, but Sakai made a last minute decision to show it off at Wonderfest first.
UPDATE: Rumors are already spreading that the MonsterArts Godzilla 1964 may be a web exclusive (while having a standard release in North America via Bluefin.) Nothing has been confirmed so take this information with a grain of salt. Also, the item seen below is the 'master prototype' for the figure.
UPDATE: Thanks to John Thomson at the Super Articulated Kaiju Collectors Group on Facebook, we now have two new pictures of the S.H. MonsterArts Godzilla 1964.
UPDATE: It has been confirmed that more news on the S.H. MonsterArts Godzilla 1964 will be available by the end of the month.
