Vintage dark blue glass cologne bottle. I’m not sure how old it is, but it’s old.
I thought this was going to be the worst of the photos I took of it, with the flash being so close, but it turns out to be the best. The depth of field was enhanced so that the background looks like it’s radiating from a distant point. The lighting added “clouds” to the fuzzy backdrop, and made it look like grass in the foreground.
