Identifying a Vintage Glassware Set?

I have a set of glassware with several different size glasses, including shot glasses, mini martini glasses, wine glasses, shifters, highballs, and taller glasses, as well as a tumbler and pitcher, with the same design on them. The highballs are the only ones with a marking on the bottom that looks like a lowercase "e" and I am having trouble identifying its maker or it's worth. It seems to be 12 of most pieces with some exceptions that were broken. Any help is appreciated! Thanks.
