Q. Do you have information about a Flower Show you produced in the early 1900s?
I can tell you that there was a National Flower Show held in 1916 at the Convention Hall on Broad and Allegheny and PHS was one of the organizers. This was a popular show at that time. (We’ve digitized the catalog which you can read by clicking on the link below).
Perhaps this is what your relative wrote about. You can also consult our history of PHS, as there were other shows in the 1900's. The digitized version of this history is linked below. -- Janet Evans
