A Gentle Reminder for Everyone

A man with curly hair and sunglasses holds up a cardboard sign in a city street, with the text 'Half-life 2 is 20 years old.' overlaid. He stands before a red brick wall, surrounded by pedestrians, including a woman in a grey beanie and another man in a grey scarf. A storefront with a mannequin is visible to the right. The image is a popular internet meme format.
