Going through my dad's old photos and keep coming across several small black and white instant (?) prints -- 2.5 x 3.25 inches with a black backing. Anyone know what these are?
yup, polaroid... in the peel-apart days. you pulled a tab, that produce a larger tab that you pulled which spread the developer gloop across the exposed print. you waited a minute or so, (longer in the cold), peeled off the print - what you see. voila' - magic!
