Print/ Signed - set of 4 framed - that's all I have!

I picked these up at a local thrift store this afternoon - set of 4 framed prints- 2 of which are signed (very light), and I can't make out enough to say more than the signature MIGHT start with an "M"?
I've attached quick pics of 3 of the 4 and a shot of the signature on one.
All framed in heavy white frames (with glass) with gold accents.
I don't know how old they are- thrift store owner had no additional information- they were drop off donations.

Any opinions on age, identifying signature, etc is greatly appreciated!
