I'm wondering if there is a meaning to the dogs pictured on these cards. This one is a sheltie, which is a herding dog and it seems to be looking at the dreams arising from the lamp - maybe getting ready to herd them and keep them together so none are lost.
I may be reading too much into it, but I'm a dog person, so I often key in on them. On the other hand, it is a specific image and you don't usually see shelties on a tropical beach.
