Lego has said it denied a bulk order from Chinese dissident artist Ai Weiwei by mistake.
The company said an internal error caused the refusal, which occurred last year after Mr Weiwei ordered toy bricks for an exhibition in Australia.
Lego board member Thomas Kristiansen told the Wall Street Journal that the confusion is "a typical example of what can go wrong in a big company".
After Lego initially refused the order, citing a policy of not donating to public projects, people in various countries began to donate bricks for Mr Weiwei's project.
In January, Lego announced a new policy of no longer asking about the purpose of a public project.
The company said, however, that it would ask customers to make it clear that Lego does not support or endorse their work.
Lego's admission comes as the company announced plans to reshuffle its senior leadership in order to create a "smooth handover of active ownership to the next generation".
Former chief executive Kjeld Kirk Kristiansen, 68, said he will step down as deputy chairman of the company in favour of his 37-year-old son Thomas.
