Zag-Zaw line of puzzles was first produced in 1909, most incorporate figurals or whimsies, sold in red, orange, or occasionally green boxes with labels on the side or bottom of the box, most without guide pictures. Initially cut non-interlocking but by 1930's became more so. Puzzles have a different cuts so that the same image will come in several versions which means that missing pieces can not be taken from other puzzles with the same image. The puzzle labels are often hand written and come with minor variations in titles and details. Some have a DESIGN category on the label. From my readings this refers to the style of cut, wavy lines, figurals, etc. See also Bob Armstrong's website on old jigsaw puzzles
Title
DERBY DAY, humorous caricatures of those attending the horse races at Epsom Downs
Item Comment
about 165 pieces, wooden, figurals, several missing pieces, with box, the same image comes as a 220 piece puzzle.-as per Wikipedia--It includes three main scenes, during the annual spectacle of the Derby, when large numbers of Londoners left town for the day to visit the races on Epsom Downs, presenting a cross-section of society in a contemporary saturnalian revel.
