Hey it's Godzilla's 61st birthday on November 3rd. To celebrate, I've photographed the front and back covers of my paper book-sized Gojira Encyclopediae (ケイブンシャの大百科 Keibunsha Dai-hyakka).
These are the only Godzilla ones I own (besides the Colour Series.) I left out the Gamera and Mothra encyclopediae, they can be showcased on their respective birth dates.
#1 is actually just a book of postcard-sized cards with no editorial. One day when I get my scanner operative, I'll scan them.
#2. An actual encyclopedia with facts and dates and pictures and trivia and Kaiju dissections!
Above #174. Below, #178, note it has the book cover intact.
I never found one for Godzilla Final Wars. I wonder if one exists...
