National Glass Co. (McKee & Bros. Glass Works) (1899-1904), Introduced: 1900
• NOTE: Roger Haworth: The opaque blue and custard are certainly McKee, the larger size of this mug and the master pitcher are certainly McKee. The chocolate, milk glass, clear, green, amber and the rare transparent blue could be either factory, although I suspect most of the production was at McKee (the shard evidence at Greentown is very limited). The frosted versions are probably McKee. I'm skeptical that this one was ever made at Dunkirk, but could be mistaken.
