A pale watercolour. Someone in a cream sweater sits at a wooden desk by a window, a hand at their chin, looking at the screen of an open laptop. A notebook and pen, a potted plant and a dark blue mug stand on the desk, and Tokyo Tower and the Skytree rise from the city outside. Lettering on the left reads “Legacy Tools — Before you send or enter, we’re here to help. If you have any questions or run into trouble, please feel free to contact us anytime.”
