Miguel,
Person at the window is perhaps the best known of these and is Dali's version of a frequently used them but it is so plain yet complex. I love this painting. The others I haven't seen before. I shall study at length.

There are definitely more versions but none as lovely as your two examples. Here is an American modern painting just to emphasize the attraction of the composition. Pretty but no contest. (I would love to claim it though).
This painting is strange but good. Proportions are mixed, very much like in some Matisse paintings where the image is more important than the realism.
Rather like a playing card where the images merge in the centre.
