While at a Monster Hunter 3 event last year I managed to get the awesome Ryozo Tsujomoto and Kaname Fujioka sign and draw a Cha-Cha on my Nintendo Wii. I felt it fitting as Monster Hunter Tri marked the first Monster Hunter game to grace the Nintendo Wii. Plus I thought I'd do it as a spur of the moment thing, I was even happier of course when I saw people with little Cha-Cha's drawn on their signed posters. I knew it was time to get the Wii out, and I must say I'm extremely happy with the finished product.
Of course it's not actually worth anything, but it's got sentimental value to me, also my apologies for the washed out image, I took it with the flash on.
