This 1949 Winchester Batteries ad was posted to the Vintage Ads LiveJournal group by noluck_boston, depicting a mother-daughter pair whose wise choice of reliable Winchester Batteries have rescued them from the terrible fate of being bitten by a deadly snake in the dark. Now they can be bitten by it in the blinding light of their flashlight. There's also a generous, 1829×1610 scan on Flickr.
