“ONE OF THE WORLD’S MOST USEFUL BOOKS”
“Some time ago I got one of your ‘Twentieth Century Books of Formulas,’ and have made my living from it ever since. I am alone since my husband’s death with two small children to care for and am trying so hard to support them. I have customers who take from me Toilet Articles I put up, following directions given in the book, and I have found everyone of them to be fine.”—Mrs. J. H. McMaken, West Toledo, Ohio.
