1965 Lister & 1965 Arts double, Basingstoke CDS

1st September 1965 Arts Festival and Joseph Lister double. Ordinary stamps with Ramsdell, Basingstoke CDS. Plain cover and typed address. Due to a backlog at the Post Office Supplies Department, a revised timetable for several of the 1965 commemoratives led to the Joseph Lister stamps being released on the same day as the Commonwealth Arts set. £60 catalogue value.
