"Sainsbury's New Shopping Hours" flyer

Flyer advising customers of changes to opening hours from 15th January [1962] including a Monday morning closure and later Friday opening. The branches this flyer applied to were closed on Saturday afternoons. This was part of a change to a five day working week across Sainsbury's (see JS Journal Jan-Feb 1962 page 9). [The hours are different from what appears to be the norm - opening all day Saturday till 4pm and either a Monday full day closing or mid-week afternoon closing - this may perhaps have been for branches in parts of central London or other places which were quieter on Saturdays and busier in the week?].
