The stand banner was designed for Bengali Wikipedia and Wikimedia Bangladesh for imparting the common invitation to the free knowledge of Wikipedia, as it was said by the founder of Wikipedia, Mr. Jimmy Wales:
Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge.
Jimmy Wales, Founder, Wikipedia & Wikimedia Foundation
As it was designed for Wikimedia Bangladesh, hence their logo is attached underneath. The whole design was on green and trees to show the eco-friendly nature of Wikipedia.
