In a Design course, as a final work, the students had to make an infography of their professional life: a Life Map. Among so many students it was clear that some similar idea would appear. One of the most recurrent was the design around the personal fingerprint.
Knowing that everyone did the job at the same time and delivered the same day, the general question was: if it's a professional job, is that considered plagiarism?
The answer for the course was that personally, rather than plagiarism I would consider it a lack of conceptual or design search. Stay with the first idea that comes to mind without deepening, neither conceptually or morphologically. What is not wrong, but in a professional is expected a higher level of self-exigence.
This is the 2018 summer campaign of CocaCola drink Aquarius in Spain and one of the great works by Steve Bronstein for Absolut, Absolut L.A. Special attention to the location of the springboard and the pool ladders:
What's the limit: the idea, the design, everything. Can Absolut say the idea of the pool-bottle belongs to them or making an advertising campaign with a pool with a bottle shape is free to everybody?
Note: I don't know if Absolut belongs to Coca Cola.
Edit after the comments
It is obvious that talking about multinationals, the responsible for the advertising campaign is another multinational. These companies usually have countless of well-informed professionals and it's clear that more than one of them knows about the existence of the oldest campaign with the bottle shape pool since, in addition to being highly promoted at the time, it appears in a significant number of sites.
For this I suppose that there is no plagiarism, copy or inspiration, more than the permissiveness of, even knowing of the existence of that design, to accept it as an alternative for the new campaign.
Maybe the designers we are visually over-informed, in my case, when I saw the advertising immediately I said Absolut L.A.! Actually to put the image in the question I had to go back to the place where the new advertising is and read the name of the drink.
Therefore, what is the limit within that permissiveness, if it exists? Or is it all OK?
