Decorated Shakers, Unusual

I find these shakers very unusual, different, yet the same. The decoration
almost looks mosaic and Im told that they were probably made by Harrach glass? I hope Im right on that.
The shakers are geometric in shape with both square and six sided shapes.
All have two piece tops and they are not often found!
PS. I know the the shaker club named the square shakers "Peeler" and they are found in a silverplate holder that was made for them produced by Meridan Silverplate co.
