A spanish book of information about Dragon Ball, "Generación Dragon Ball", published in 2008, by Daniel Quesada and Jacob García,
there is a section talking about AF:

It says:
"Curiously, This drawing was sent and published in the number 92 (May 1999) of the magazine "Hobby Consolas", inside the section, "Teléfono rojo". The image was signed by someone called "David Montiel". It's the origin of all this in Spain? Probably, because it's impossible to find a previous version of the one which was published on this number"
Also, Daniel Quesada, one of the authors of this book, works in the magazine Hobby Consolas too.
