A Belgium-based designer has expressed surprise on social media that the emblem for the 2020 Tokyo Olympic Games unveiled last week closely resembles the logo for a theater in Liege, eastern Belgium, that his studio crafted.

"I cannot judge whether it was stolen or inspired by my work. I'm consulting with my lawyer," Olivier Debie said on Wednesday, adding that he expects to decide this week whether to take legal action.

The 52-year-old a photo posted on Facebook of the two works side by side a few days earlier, expressing the amazement he felt when he saw them. In a separate post, his studio also said "There is a striking resemblance between the two logos."
