Well, there is this notorious map, of course
The people who came up with this at least were fairly comfortable with safely tucking germany away behind the iron curtain.
(Though now I can see they cleverly added the Rhineland at least to the western European state, which is a really smart move, as this is basically an industrial backbone between the alps and the dutch ports; but again, the choice seems to be strategical rather than cultural)
Things changed with the end of the cold war, of course, with most of eastern europe opening up, but I also get the feeling western germany was considered somewhat of a borderland (duh), not really part of the sexy, tourist-y notion of Europe (from, say, an American or British perspective) that is pretty much limited to the dark blueish areas of this map.
I'm not sure everyone outside germany sees it as entirely "western" to this day. For one thing, in pop culture you occasionally get like stereotypical germany/transylvania/eastern europe mixups (things like Terry Pratchett's Überwald, Unterland in the 'Venture Bros' and the Xylvanians in 'Battalion Wars' come to mind), perhaps due to he fact that german speaking populations were indeed quite mixed with eastern european nations in the past, especially if you factor in Austria-Hungary.
