What better way to celebrate the first day of summer than a little grilling in your own backyard? This is a cheerful scene- you can make out the man's smile and the woman's laughter. The woman is wearing what I imagine was a very brightly colored apron with a fruit pattern. In one hand she's holding a fork and with the other, she's turning a crank on the grill. From what I've read, the crank would turn a small fan underneath the grill that fanned the flames.
If you know who this lovely pair may be, let us know in the comments!
