Now Cryselco stands for the CRYStal ELectric COmpany, and they made electric lamps and light bulbs, for the home, for automobiles, and also as Christmas lights, for the home, sold pre-stringed in attractive boxes.
They also issued three sets of cards, “Buildings of Beauty” (CRY-030 : CSH-2 :1938), and “Beautiful Waterways” (CRY-020 : CSH-1 : 1939), both of which were sets of twenty-five brown gravures measuring 101 x 76 mm; I am not sure why the later set is listed first, as it is not in date nor alphabetical order.
Then there was a bit of a gap before they produced “Interesting Events of Sixty Years Ago” (CRY-040 : CSH-6 : 1955) , which was a set of twelve grey-black cards with light yellowy browny borders, extra large in size, measuring 113 x 88 mm, and first listed in part II of our original British Trade Issues Index, of 1969.
