Need help with this painting

Hi everyone,I have som paintings i really need help with,I have already been trying to figure out who the artists is on these.
Would love if someone could help me with any of these 3 art nr 1 is a figure of woman, second is a mother and a baby last one is a lithography "harmoni". Best regards from Sweden ❤️

 

The first appears to be a student work and the second appears to be a painting done from a 1950s photograph of a mother and her child by an amateur artist. Unless you know their provenance, I would think it almost impossible to identify the artists. It's a long shot but... You may be able to identity the artist of 'Harmony' print, the most accomplished work, with a Google Image search.

Ljubomir Ljuba Popovic ? Harmony? The signature seems identical. Thank you for your help ☺️

Certainly not unlike his signature but... Ljuba was a Surrealist. I don't see any of his work, including his multiples, that look like yours. Not in theme or in execution. I suggest you contact the artist's family via his web site to verify/not.
