Woman in a white shirt and black skirt standing in front of a pink…

Tree with a plaque on its trunk adorned with pictures and text

Open book with a drawing of a cube on it

Close up of a plant with green leaves and thorns on it

Old map of the city of Sacramento

Close up of a person&#39;s hand holding a small green plant

Ruler next to two ancient coins on a white surface

Yellow building with a red door and stairs leading up to it

Man riding a bicycle down a street lined with tall buildings
