I remember, as a teen, getting both the Whitney and Warshawski catalogs, thinking I was going to do some serious price-comparisons! They both published illustrations of their big stores . . . Once I really looked at them, I realized it was the same building but portrayed from two different views!
The building was huge and it fronted on two streets . . . the building had one company's name on one street and the other company's name on the cross street! Just as Joe said: no matter which entrance you used, you were in the same building, same store!
I was disillusioned! Then I laughed about it every time I thought about it. I always wondered how many people went through life buying both catalogs and thinking they were competing companies!!
