Spectacles Speculation

There are no specifics as to where these special spectacles arrived from; they just were lying next to the garden wall hidden in weeds, slightly dirtied, neatly folded up, and with only a minor scratch. I've asked my roommates, nope...asked my downstairs neighbor, nope... Perhaps they fell from the balcony of one of the neighbors behind the garden. I'll have to ask next time I see them. They were not, by the way, set as the photo shows with an oxalis nose and a grass smile; that was my doing. :-p
