Here below is the eggbox made of pewter, on its maiden flight undergoing trials.. It will be given to my sister at Christmas as suitable stowage for the produce of her flock.
And what will be left behind to convince sceptical audiences of what was there but has since flown on its way. The footprint of the eggbox will remain, the space in the casting blocks where once it existed. An empty packet that once held rods of solid pewter. A bit of text, a tiny clip of video.
