In the old days, the catalog sold rockets to the hobby market with pictures of the experience. Today, they sell to the experience market with a simple pic of the product. They assume, or perhaps have determined that the average customer lacks the patience to actually build a rocket, so certainly they are not going to read about each one. The old catalogs gave a better sense of the rockets in action, the new ones are static, and in my opinion do not serve the company well. I also recall that the older catalogs included the technical section., which is now a separate purchase. This all points to the fact that a small family business is intrinsically better than a corporate owned entity, Vern was interested in educating his customers and keeping their interest. Cox seems to be satisfied to sell everybody a couple of rockets.
