The image shows a white paper hanging on a green wall. On the left side of the paper, there is a handwritten letter written in black ink. The letter appears to be a thank you note, as indicated by the title at the top of the page. The paper is slightly crumpled and has some writing on it, but it is not clear what it says. 

On the right side, there are two small posters hanging on the wall. The first poster on the left is a poster with a colorful illustration of a child's face and the text "Thank you for your support". The second poster is a small poster with the same illustration and text. Both posters have a blue background and white text.

The overall mood of the image is one of appreciation and gratitude.
