This photograph came from an original collection of family portraits in an album; a collection that has been together since the 1800s. 
In the front of the album is written: 'This album present to Mother by John Milne, Grocer of Mauchline. JBW.' Mauchline is a small town in Ayrshire, Scotland. 
JBW is likely James Williamson, a family member, because another note in the front of the album reads: 'Pencilled notes made by A.B. Williamson of Portsmouth from dictation by his Father and Mother (Mr & Mrs James Williamson of Ayr) Oct. 15th 1935.' 
Most of the photographs in the album had pencil notes beneath where they were placed, identifying the person and sometimes even their job. 
This auction is for one photograph from the album - not the album. 

The photographer's name is rubber stamped on the front and rear of the card, suggesting a newly established business or a small business - 'J.C. Esslemont, Photographer, 35 & 37, Back Wynd, Aberdeen. I could not find any references to this photographer. The note written below this photograph read: 'Bob Eason (Aberdeen) Traveller.' Eason may have been a traveller (salesman) while he served as a volunteer.
