Bill Bubble Guy must not have known that the two toy desks used the exact same mold. I think they even have the tops painted the same color, so the only way to distinguish them as far as I can tell is the color of the front and sides.
Pops' was the darker one, Newsman had the lighter one.
But very few people would catch the mistake if you got it the other way around, so just do what feels right for your display.
