1937 40-page "Follett Picture Stories of Industry" (front cover bubble) series; this one is on Coal.  It appears geared to a primary audience of school children, singing the praises and educating children on the mining and uses of coal. Overall in VERY GOOD CONDITION.  There is corner wear and lighter edge wear, a previous owner name on title page behind front cover, no further marks, lots of B&W photos as shown in listing photo.  A nice example of 1930s industry advertising booklet aimed at younger school children.
