Help identify - who he is and what is it?

[Анатолий Шарий]

As I understand it, lithography.

Canvas has a rear-type forged signature - "Winter nach C. Gugel" Below the signature "aug Beckers (?) Kunstverlag Munchen"

 Unfortunately, nothing could be found about this organization. Tell me, please.

The front of the painting are two (!) Signatures - one with the letters and the year 1860, the second with the letters and the year 1859. Apparently, the 1860 - year of establishment of lithography. However, the signature on the 1859 does not correspond to the signature of the artist Carl Adolf Gugel (1820, Bergtsabern - 1885, Munich)!

The second picture is the same for the execution, as a twin brother, but without a signature. It shows a woman with a child in a different interior and signature rear "Herbst nach C. Gugel", which means "Autumn Gugel. This, as I understand it, was a series of paintings, but to find any Join the Internet is impossible. Dimensions for both - see 60:70

I would be very grateful for any information - that is, and how much could it cost? Very interesting.
