Not Fenton ... but a very fine example of early American glassware!
The pattern is called Guttate, and it was made by the Consolidated Lamp and Glass Co. of Coraopolis, Pennsylvania, in the 1890s. A salt shaker called simply No. 96 is pictured in an 1894 advert shown in Mel Murray's fine book devoted to Fostoria, Ohio, glass (p. 156). The Fostoria connection is due to the fact that glassmaker Nicholas Kopp moved from Fostoria, Ohio, to Coraopolis. Kopp was responsible for the glass chemistry, and he made wonderful things in blue, yellow, and the pink we see here.
