This one, entitled "Quelle
Famille! / La Bande à Mickey" ("What a Family!" / "Mickey's
Gang") has been published in 1988, on pages 16 and 17 of the French "Journal
de Mickey" #1901 (it was the second issue of a special series celebrating
Mickey's 60th birthday). It's not exactly a family tree, but rather an
illustration showing all the most known member of Mickey's gang : The Phantom
Blot, Chief O'Hara, Morty and Ferdie, Gloomy, Doctor Einmug, Goofy, Captain Doberman, Pluto, Minnie, Sylvester Shyster,
Mortimer, Mickey, Clarabelle, Bad Pete, and Horace. The character in the
lowest frame has been called Mortimer and represents Mickey's first steps
(if you look closer, you can see that the character wasn't intended to
be in a frame, but to stand with the other little Mickeys, but tey later
decided to draw a frame, then they colored his body in brown so we think
it's a part of the tree but they have forgotten the feet... Computers weren't
what they are now...)
