Artist Accuses Disney of Stealing His Work for 'Solo: A Star Wars Story' Posters
They do look quite similar.

After character posters for Solo: A Star Wars Story were unveiled, a French artist stepped up to accuse Disney of stealing his artwork.
Artist Hachin Bahous is noting that the new Solo character posters look suspiciously similar to a set of album covers he designed for Sony. Designed in 2015 for a music anthology, the covers came well before the artwork was released for Disney’s Star Wars standalone film, arriving this May 25.
Looking at a comparison between the artworks in question, the similarity is definitely undeniable as a similar composition and color palette is seen. Bahous who took to Facebook to voice his displeasure is currently only asking for credit and payment with no signs of any further legal action.
In case you missed it, Hasbro recently presented its first batch of Solo: A Star Wars Story action figures.
