Above picture may not be very clear, but then, it is a reprint from an old english journal, the Examiner, that in its edition of december 30th, 1936 had this picture and a note about a "fairy tale cottage in Lancashire".
According to the caption J.T. Halstead (1866-?) was a mill operative in Rochdale, who, probably when retired, began decorating the exterior of his house with broken pottery, shells, figurines, a plate in memory of his deceased dog and various smaller items (teapots, light bulbs etc).
I have bee looking around for more details about this environment, but the internet so far has offered no further information, except this trailer (0'47") of a 1937 item on British Pathé, showing Halstead at work (for preview only, DVD can be bought).
