[2]Here is a leather neckerchief slide from the 1958 Area 2-H Conclave. According to the OA Conclave Handbook by Dingwerth and Jensen, this is the only issue for that conclave. Can anyone confirm if this was the only issue?

Not sure who was the host lodge or where it was held.  The image is of a bear hide rug, which would seem to indicate that the host lodge may have been Wakanda Lodge #186 who had a bear as the lodge totem. This however is just speculation on my part.
