MARINE REVIEW January, 1926 Investigate Before Investing Every advertiser—whether national or local—owes it to the best interests he represents to fully inves- tigate every publication’s claim for circulation, etc. before he invests in ‘‘white space” advertising. It is the advertiser’s right to demand facts, not theory. Superficial information is not the kind on which to build a successful advertising campaign, and unless each copy is delivered and read, the advertiser is paying for waste circulation and his advertising dollars are not producing proper results. By our membership in the Audit Bureau of Cir- culations we safeguard the advertiser's money, for we want it known, that we make no claims of any nature that are not fully substantiated with A. B. C. verified reports. Get our last report. Know what you are buying. Then invest. Marine Review Member A. B. C.
