I don't think it's popcorn. My first guess was that it looked like the spray foam used for insulation that becomes light and brittle when it dries. Could it be that, crumbled into little chunks? I could also see cat litter as a possibility, as Maverick says, but I'm not sure that type of litter was around when that photo would have been taken.
You realize I've spent two days thinking about this!
Phew...I nearly had pre-withdrawl withdrawl symptoms then...if it's not popcorn it's paper-crumble kitty-litty!!
