Help identify antique painting

I found this yesterday at my local thrift store. But when I asked my friend who is the manager how much he wanted, he said $50 !

Neither one of us could make out the name, so he agreed to keep it in his office until I could ask the miracle workers here!

So, my friends, can anyone tell who the artist was of this painting?

Thank you!

 

I think the lable on the back ends with 'Pfandlhof' (Austria) Other painting with what seem to be the same buildings

 

First line on the back: Wilder Kaiser
That's the mountain.
