so far i think they are, but if anyone find any that are not, then please just say and ill redo
nothing can be "read" in the icons as they are small (mostly 52x52 to fit in the 64x64 square), some are very similar shapes to some products of today, but i very much doubt that those ones can be said are copyright
ive altered the "labels" of each one, to show, its system cheapest selling point (or as in the case of rheinbier thats obvious)
would these now be acceptable
also before i do the upload, i would like to make an alternate for every icon, some at the moment cant be done, as fl uses some icons as a "generic", eg toxic waste icon is also used as the "cargo pods" for the trains
