This glass type comes up often in discussion by many names and almost as many attributions. Samuel Clarke, British candle maker, called this pattern "Zebra" in his 1890 catalog. It comes in both fairy and pyramid sizes with clear Clark Lamp cups and sometimes with a matching lamp cup and bases. According to Clarke's catalog, it came in pink, blue and green, red and yellow, and mottled.
In addition to potential British and Bohemian manufacturers, there is a theory that many of this type (not all) were made by the Northwood and Phoenix Glass Companies in the US.
