Copyright law is complicated and varies greatly depending on many important factors, it only becomes more complicated when it begins to deal with intellectual property and trademark law.
Your best option is to consult a copyright lawyer in your jurisdiction for advice.
IANAL, but based on my limited understanding. Ownership of the copyright of a work does not necessarily grant you the right to freely sell such work, only to restrict others from doing so. For example, in some countries it is illegal to publish or sell any image that contains a person unless he has obtained a model release of that person. You cannot publish or sell the image because its similarity is in it, and you cannot reproduce the image due to its copyright.
On the contrary, in New York, this is based on the expectation of privacy. For example, I can take and sell a photo of someone sitting on the street, but if they are in a sidewalk cafe with some kind of barrier, although I can see them from the street, I cannot sell the image because they are not considered as "in public".
When passing from the image of a person to a brand (what could be argued is the public image of the group of people represented by the corporation) many additional considerations apply. In fact, the answer could be completely different for different brands because each one will have its own licensing policies and practices for its brand.
I hope that gives you an idea of the complexity of some of the problems at stake, and I am dramatically simplifying things to prove the point. Again, if you are concerned about copyright, contact a lawyer for advice.
