This is from an article from September/October, 1947  ARS magazine:

Under the sponsorship of the Philadelphia Rose Society, the Home Gardeners’ June Rose Festival was held in Gimbel Brothers store on June 11 & 12 (*1947) with over 35,000 people attending. Participating in the festival were general garden and plant life groups, private clubs, a department store, public rose gardens, private gardens, arboretums, commercial firms, schools, colleges and universities, representing three states and over 25 communities.

Of the 200 rose varieties listed, over 6500 blooms were exhibited for which 150 awards were given.  One person displayed 1000 roses of his own growing.  The festival was staged in all details by housewives who are amateur rose growers and who had never managed any such showing before.

At the June 12 meeting, Dr. R.C. Allen, Secretary of the American Rose Society and later became President of ARS, presented a lecture, “Modern Trends in Rose Growing”which was greatly appreciated by everyone.
