Fake or original paintings?

[macas]

Dear Colleagues,

On ebay , some are works by famous artists of the Paris School . What do you think about the authenticity of these works ?

1. Michelle Kikoyn , Oil on board 50 x 35 cm;
Picture 1.6

2. Leon Bakst, akvarel , 38cm x 28 cm
photo 07/10

3. Isaac Dobrinsky , oil on plywood , 49cm x 38 cm
Photos from the trail . message

In my opinion, all three are fakes.
