Rare Vintage 'On the Trail of Marihuana' Book The weed of Madness 1939

Explore the intriguing vintage book 'On the Trail of Marihuana' by Earle Albert Rowell and Robert Rowell. The book measures 5 1/2” x 7 3/8” it does have some external soiling and wear - pages 5-13 have discoloration/ stains in the gutter of the book. The back board had something sticky on it at one time. The back blank end page has Yes written in it…which is kinda funny… Please see photos as they are intended to be part if the description. Im picky with my books so overall it is in pretty good condition and internally clean (excluding the little bit of gutter staining) and in very sound condition…and it is a hard to find book - denouncing the use of cannabis. 1939 Pacific Press publishing association Reasonable offers are appreciated Thanks for looking!
