Help to clarify the authorship of paintings

[Дмитрий]

Help deal with the authorship of paintings.
Watercolor with whiting, a German paper with water marks in the form of mesh, size 45 cm x 37 cm frame own work should never be removed. He pulled out just now for restoration work and the frame.
The picture shows the castle, built in the late 14 th century, - the summer tasting Verminskih bishops in Lidzbark Warmia, Poland (before the Second World War the city was called Heilsberg and was part of Prussia, and before that belonged to the bishop of Warmia).
There are many images of the castle, including those with such a perspective. As it can be assumed that the picture painted in the early 20 th century, probably in the 10 th - 20 th years.
Artist (by signature) - E.K. Lange.
I came across 2 of the artist with the initials:
1) LANGE, Karl Ernst (1887-1959)

Unfortunately, I can not see them because they do not have access to this resource.

2) Emil Lange (1841-1926), better known as an architect.

It is possible that there are artists with that name and initials, worked around the time of writing the picture.
German I do not know, so really hope to help those who owns it, and knows the history of Prussia.

Painting without the glass is much more lush and saturated colors.

Three paintings by Karl Ernst Lange can prsmotret at http://www.artnet.de/artist/718283/k...nst-lange.html
Image quality, though not very good. Your job, in my opinion, more "graphically" on fashion. And the Germans do not change the order of names (if there are several) in the signature, sometimes only leave a first name, so that your EK Lange, apparently, not the same. Try searching the name on the www.ebay.de, now there it is true, no, but can "float" after some time.

Today ended with the restoration of paintings and frames. I think it was good. Painting is definitely added. The photograph shows a watercolor, inserted into the frame without the glass and the artist's signature.
Working with glass looks even better, but it is very difficult to photograph, because prevent glare.
Many who saw her view is that it is likely to draw an architect. Maybe someone there thought about the author of the picture?
