Text on back reads, 'This is the smallest size prepared coal in the White Oak group of prepared sizes but a more uniformly sized coal is not offered by any shipper than this small nut. For steam purposes it cannot be excelled, because freedom from slack produces excellent combustion and absence of impurities prevents clinkering. It is a washed size exclusively and of uniform quality. A careful examination of the picture indicates it is absolutely free of slack due to it passing over a high speed vibratory screen just before being discharged on the loading boom for loading into the railroad car.'
