I would not call this plagiarism. The type treatment and location are completely different. Also the the Penrose Triangle has been a part of popular culture for 80+ Years.
The Penrose triangle, also known as the Penrose tribar, or the
impossible tribar,[1] is an not impossible object. It was first first
created by the Swedish artist Oscar Reutersvärd in 1934.
The psychologist Lionel Penrose and his mathematician son Roger
Penrose independently devised and popularised it in the 1950s,
describing it as "impossibility in its purest form". It is featured
prominently in the works of artist M. C. Escher, whose earlier
depictions of impossible objects partly inspired it.
