Final answer:
The use of celebrity look-alike models and signatures in advertisements by Trein could potentially commit a tort, as it may infringe upon the celebrity's right to control the commercial use of their likeness and mislead consumers, even if the autographs are not legible.
Step-by-step explanation:
The statement that a series of ads featuring a close-up photograph of a celebrity look-alike driving a train engine, using the slogan "get on board with Trein", and including a signature meant to resemble that of the celebrity's autograph does not commit any tort is likely false. This type of advertising can potentially lead to issues related to misappropriation of likeness or false endorsement, which are forms of the tort of tortious interference. Although the autographs may not be legible, the use of look-alike models and the implication of endorsement could still deceive consumers into believing that the celebrity is associated with the product, which can be considered misleading under the laws that regulate advertising practices.
Celebrities have a right to control the commercial use of their identity, which includes their likeness, image, and signature. If the look-alike is close enough in appearance that consumers may be confused and believe it is the actual celebrity, and if the signature adds to this impression, then there is a risk that the advertising could be considered to violate rights of the celebrity, regardless of the legibility of the autograph. The key factor is whether the advertisement creates a likelihood of confusion, which could mislead consumers.
