The work semester - excellent results!

The image shows a poster depicting a young man and woman standing on a wall. The woman is wearing a green jacket and an orange shirt, while the man is wearing a helmet. They are both workers possibly in construction or industry. The background of the poster features a striking blue sky with many white clouds. The colors in the image include shades of green, blue, and brown. The overall theme of the poster appears to be related to labor, possibly from a communist era propaganda. The text in the image is in Cyrillic script and translates to "Labor semester - excellent!"
