What's Wrong With This W Picture? Poem by Hubert Wilson

Don't know where, don't know when?
Explanations nil on where all these years this picture has been?
Cropped out nearly all identifying information?
Even the mystery location?
Photographed by who[sic]?
The enigma just grew - could it be you?
Indeed this 'magnificient thirty-seven' -
Only the utmost divine leaven -
No doubt this picture is pure manna from heaven?

Judge for yourself?
