GARAGE SALE - 4 PAINTINGS CIRCA 1960'S FOR $100 GOOD DEAL?

Hi all, I found these today at a garage sale (a friend who knows I'm a sucker for art called me & told me about it) and think I did well - the paintings were left by the seller's uncle & he thought they were all from the 1960's? I got the 4 for $100.
Any thoughts? (No factory art please!)
Also, I need help with the 2 large ones' artist's names? The mid century I think may be Duchamp?
And the antique one looks like Kudden or Kudder?
Either way hope you enjoy them!

 

Final one

 

Hi,
The one of the Brooklyn Bridge is a factory painting. The last looks like a Vemirrer (sp) girl with a pearl ear ring. I think they are all copies of famous paintings.

not a good buy imho

 

Greg is right

 

I wouldn't buy any of them for resale, or for my own home - but if you want them for your home the price isn't bad for all four.

 

For re sale not much value. More decorative

 

I quite like the Brooklyn bridge, good mod decorator piece, sell it as school of Buffet ....others are rubbish.

 

For unknown reasons , I think the painted girl above could be Raquel Welch, done from a Playboy magazine, but it looks nothing like her above and perhaps not...

 

Poor Vermeer, here’s another version found in a Charity shop. The dog with the bonio earring.
