If you ever visit San Francisco make sure to see the San Francisco Botanical Garden in Golden Gate park. It has countless clever and subtly humorous signs through out the park. Below are two examples. Both has a simple yet explicit design, can be understood by a variety of cultures and bring a smile to my face. The bare foot about to step on the delicate flower has an expressive upturned toe and the bee wearing headphones is cooler than ninety percent of the t-shirts I see while strolling down Valencia Street.
