VIRSENE' VS IMITATIONS
T h e Versenes are our products. W e originated and developed them. We alone manufacture them. T h e y are good products. This is pointed out b y t h e fact t h a t others are now beginning t o imitate them. I n one sense this is r a t h e r flattering because it indicates a n actual superiority of the Versenes. B u t in another, it creates a confusing and somewhat deceptive situation for those who actually prefer t h e original Versenes. VERSENES VS COMPARISON
" J u s t like Versene," " j u s t as good as Versene," " t h e same thing as Versene." These are all sales arguments which imitators m u s t use. And, it is interesting t o note, t h a t it is extremely difficult for t h e m t o even explain their imitations without direct comparison to t h e originals. VERSENE1 SETS STANDARDS
