"The store is Euronics of Catania, Italy (an electronic shop similar to America's Best Buy).
The wall deco belongs to Euronics, not to Samsung.
Euronics has been decorating their walls with trademarked logos for some time.
The original article is from the Italian press and actually focuses on the interesting "coincide' of both Samsung store-in-store and Apple store opening on the same day in the same mall.
That appears to be the case. This is apparently not a "Samsung Store", but a separate display area dedicated to Samsung products within the Euronics store. The store looks very similar to a "Best Buy" or "Target". Some on-line images from different Euronics pages show logos, sometimes grouped in various departments. Just like what you'd typically see here in a large electronics/department store.
Vindication and much ado about nothing when all is said and done. You can cancel the appointment with the hangman now.
