I thought that some years back Lionel promised never to make beer/alcohol or tobacco cars again. There are probably some regulations prohibiting the decoration of toys with these logos, hence the designation of 21+.
What goes around, comes around. I've read that ome old tinplate beer/alcohol cars from Germany are generally found with the decorating blanked out. I am certain one of the tinplate guys here can elaborate.
All I know is, having beer/tobacco/alcohol decorations on some of my rolling stock never gave me the urge to indulge.
