Last year, I shared five of the six 1978 Stuart Pharmaceutical calendars from the series numbered DM-17301 to DM-17306:

1. January/February(George Goebel Collection)
2. March/April (HHCE Collection)
3. May/June (HHCE Collection)
4. July/August (HHCE Collection)
5. September/October (Missing)
6. November/December (HHCE Collection)

And today, I share the missing September/October (DM-17305) calendar, thanks to Roger Dreyer at houdinireavealed.com and an alert from John Cox.
