Would JWs see this as a conflict of interests or would it just not be of any importance where the Awake artwork came from?
There are numerous examples of the Society's plagiarizing the work of other artists. Johnny Walker Red's sunset, Stern magazine's swimming nymphettes, So-and-So's Bible story characters, etc. The nature or origin of WT artwork - whether subliminal or plagiarized - is of little interest to most ex-JWs. I imagine an ardent JW would not see any issue. Personally, I feel WT artwork is manipulative, dishonest and scary on numerous fronts. But it is colorful.
