The Beatles 5th album was released in the UK on this day in 1965.  The US release followed a week later.  The American album included instrumental music from the Help! movie, bumping two of the songs on the UK. Those appeared on Rubber Soul and Yesterday and Today.

The arm positions they choose come closest to the letters
