A year old tree with a single leaf. Tree branches on a blue background. Yellow and blue in the photo
A man and a woman, he and she and love between them, a single heart for two
Dry grass and a single tree against the background of clouds
Sunset sky with a single-engine Soviet Su-9 aircraft
Cessna a 185f single-engine aircraft soars in the blue sky
A universe with planets and stars centered around a single race
