3 Paintings found in thrift store - 1 may be a real Antoine Blanchard? + Who are other 2 artists?

I found these today (2 of 6 paintings & lithos/prints + a BIG carved tiki (I think) wood mask I ended up buying today!)
The first is signed A. Blanchard; it is a oil on board in fair condition. When I googled the name I came up with Antoine Blanchard & saw some really nice prices people were getting/asking for his work! But I also saw something saying any paintings by him should be verified because he's apparently copied a lot?
Any idea if I have a real one?
The 2nd one looks like J. Sacks or J. Sachs?
And the third one I don't recognize at all but I like it the best! (lol) - The name looks like Azipi... but the last part is behind the matting, so I can take it out of the frame if I need to.
Can anyone tell who the artist was for that one?
Thanks all!
Happy New Year!

 

The antoine Blanchard i believe is a copy l. The signatures are different from what i am finding online. He seemed to sign his work with his full name and the style is different. Still trying to find the other 2 pictures.

 

Try paul Augustin aizpiri for your flower signed print

I like the way the trees are done in that first painting - almost brutalist, but not what I see in Antoine Blanchard works.

 

The question with the Aizpiri is: Do you have an original print, or a cut-down poster?

 

Maybe this person? Siggie looks similar, work varies in quality.

Your Blanchard is not by the Antoine Blanchard - who also painted under another name BTW

Your still-life is cool tho

 

I'll try to open back to see - thanks!

 

I think your right (dang it!) - thank you!

 

That's it rink28! & I think mine is a original print instead of a poster; but I'll have to open back to check - thank you!
