Good question. I think it was around for a long time, but I don't have a closing date in my notes. It opened about 1920 and was still around at least until 1930. Might be able to add a decade or so to that with a quick trip to the library.

The ivoroid dice don't show their age as much as the transparents. I have plenty that are from the 1930s that don't look any older than these.

Unfortunately the Taylor records that these are in are undated, but most of the other dice listed with them were made for places that were active in the 30s and 40s. The more recent ones were 1950s.
