Drinking glass set

Set of 10 Drinking glasses. Glass #1 has measurements of 8-inch height, 3 1/2-inch width, and 4-inch depth, while the rest of the glasses have a measurement of 7-inch height, 2 3/4-inch width, and 3 1/2-inch depth. Glass #4 is slightly smaller than the rest because I'd assume human error. All glasses have pontil marks on the bottom from glass being separated from blowpipe. Unknow if they are crystal or not. All are believed to be hand painted.
