Because tobacco advertising & toys, amongst alot of other things, are a no-no these days -just look at some of the F1 Ferrari Model cars who were also sponsored by Marlboro at the time.
Anyway, decals i can live without, Reprolabels will fix that anyway, but i'm so glad that they have the Marlboro Chevron & not some other wierd abstract shape approximating it.
As for the number, i couldn't care less. It's a freakin' Marlboro Wheeljack in Masteriece form. I'm preordering this sucker on sight.
