Plenty text and feature either red or blue portraits of them. Reverse of each knife has arrow designs pointing upward w/text "Crimestopper Whistle" and "Clue Detector." Whistle is about 2" long and folds out. Clue Detector is .75" plastic magnifying glass that folds out from left side. 2.5" long blade is marked w/maker's name "Camco." Knife and included red gimp cord (usually missing) are essentially Mint although as w/all examples, by the small brass rivet on front grip is a tiny crack barely showing above and below. Usually as made as all 4 rivets have this problem so these examples are much better than most and knives are as nice as can be found. c. 1950s. Display has edge wear, mostly at corners w/heavy 3/8" crease to die-cut area at top right. Fine. Comes w/original but non-descript well worn box.
