Butler Brothers Catalog Ad - A potential source for Czech glass exports ID

These images of the export Czech glass decorative items of late 1920s to early 1930s were put together in 2012 by Tom Felt in Monograph 121, for our use, the Czech glass collectors.

It's an interesting identification tool, the general approach by BB was to group the same producer's glass together in large assortments, and even smaller groups of 2 to 4 pieces. Like most practices there were exceptions. Recently Tom Felt of The West Virginia Museum of American Glass Ltd., stated that he still considers the BB assortments to be by the same producer with few exceptions, this was after I found one of those BB exception, a multi American glass producer ad in the "Fenton book, the first 25 years", and asked him about it.

I know since 2012, many of us have studied the pages of export glass shown and advertised. It has been satisfying to be able to match some pieces to a producer, and also frustrating when some glass pieces shown have never been found.

I am posting 4 examples of groups and assortments. Which I think all belong to one glass house, yet I do believe this was not 100% consistent, where a few ads might be a mix, you can see they used a cut and paste approach to illustrate the glass items advertised, it would not be difficult to assemble an ad with some pieces that were from different companies, due to some extra glass items not selling well alone, or a change in prices during the depression years, putting together more economical offers. Those very large assortments, which we only see a small portion of.

These attributions are my own, and do not necessarily agree with other collector's opinions.
