I fell in love with this print by John W. Golden because it reminded me of summer in the States when I lived there many moons ago as an exchange student.
I was enamoured with fire flies, and would spend countless evenings sitting out the back watching them flit about the sky.
I highly recommend you take a look around this etsy shop, so many brilliant series of work. And particularly loads of cool pieces for little people's rooms.
