Now that I too have learned how to post pictures (thanks Vilkata!) I can't withhold you the sight of these two Interior Views, that were sent to me a long time ago, by who I can't remember, and the source was never given: obviously from some book. Anyone knows where they were published?
Dont know for sure but it really looks like it came from the DK Encyclopedia on wwi the style of the lay out is very simmilar to fouldouts from the DK series.
