Goodbye & Thanks

I've been looking for an image to say Goodbye with. This is a piece of Art work, along the river bank, that I walk often.
It's accompanying text talks of how it represents illusion and reality. The text inscribed in the glass is from Milton's Paradise Lost : "They hand in hand with wandering steps and slow, through Eden took their solitary way ".

Thanks for your years of generosity, kindness and warmth as we've wandered through Blip.
