That's an OBG-1968-
Not really a "reference book" ...
But nice to have in the book collection I think...
-this oldie (1968) was missing in the library. So I told Missus B. today. Problem solved..That is a good old one, but there comes a point when you haven't opened a book in years that you realize too many of the books on the shelf just have the same old information over and over again just in different formats.
I like the newer books with all the beautiful color pictures of original items Verlag and Johanns books are the ones I find myself looking at recently. Of course, you need to have some of the old classics when you need specifics, but you already have all of those.![]()
