These might be nice cards for stand-alone display racks, but I don't know about their use in the typical floor stand found in hotels etc.
In the multi-card racks often only the top 1/3 of the card is viewable -- so the top 1/3 of the card has to have the catchy graphics that will cause it to be picked up out of the rack.
I've been aware of this situation of rack cards for some time. But it was very well demonstrated during a presentation by a marketing consultant during this years annual conference of the Association of Railway Museums. The host museum (Pennsylvania Trolley Museum) had had success using the consultant who does international work and engaged him for several sessions on marketing during the conference.
