The composition that we find in front of us here is the amendment of reality, where Dali wanted to challenge whatever we are used to seeing. Therefore, a car is only partially there, with large elements missing, and then it appears to merge into the landscape behind it. Plants are placed within the vehicle to further give an impression of a man-made objects merging into a natural landscape, a little bit like when a sunken ship is slowly reclaimed by the natural world. The landscape used here is desert-like, in line with the dry environment in which he grew up as a young boy in Northern Spain. The same colour scheme appears throughout his surrealist period.
The artist also creates holes within the rocky landscape, perhaps suggesting that the car itself has emerged from behind, as if produced organically. It is hard to precisely comprehend quite what we are seeing because the artist was deliberately avoiding the purity of reality and wanted to confuse and excite his audience. He was known to have studied a number of different theories during his lifetime and would use them as inspiration in his work, as well as combining them with genuine items from reality but combining them in ways that one would not normally see. This helped to make this artist's paintings initially shocking, and then they provided further interest as you perused the rest of the composition.
Sadly, it is a part of a private collection but followers of the artist can find many other artworks from his career in a variety of galleries and museums around the world. There are a number of institutions that are entirely focused on this artist, though another array of his pieces are also spread more sparsely across other venues. Always check ahead if you are interested in seeing a particular painting, as loans are very common these days and curators will often seek the help of a number of owners in order to put together a particular theme for their planned exhibition.
