The creations of sculptor Arlindo Armacollo, 77, were first made for a church in Paraná, south Brazil six years ago, but have recently gone viral and caused an international debate over their bizarre appearance.
One Twitter user described the statues - made from shop mannequins, orange peel and and 11lbs of beeswax - as a 'Brazilian Horror Story' while others pointed out the statues of The Queen, Micheal Jackson and Nelson Mandela were 'questionable'.
Critics of the artwork, which is now displayed at a museum named after Armacollo's father, were quick to give their opinion, with one writing on Reddit: 'At least they tried'.
Another wrote: 'They looks like 80s action figures blown up to human size scale.'
A third said: 'Were these wax figures done by the same guy that did Cristiano Ronaldo's bust?', in reference to the widely ridiculed statue of the footballer that was unveiled in 2017 at Madeira Airport.
Someone else wrote: 'Why is Marilyn Monroe looking hench AF?', while another shocked commenter said: 'The pure fuel of nightmares'.
Another person commented on the Princess Diana waxwork: 'This is more offensive than any debate about an episode of The Crown will ever be.'
Other famous faces on display at the museum include late singer Elvis Presley and Western star Charlie Chaplin.
The artist also created the figures of academic Albert Einstein, former US President John F. Kennedy and Mahatma Gandhi.
The sculptor also made a statue of the activist Martin Luther King wearing a black suit with a tie.
But the septuagenarian artist isn't bothered by the criticism, and said the art isn't 'about making money'.
Speaking to the Guardian, he said: 'I couldn’t care less. If it was about making money it might bother me whether people appreciated what I was doing or not.
'But I do the things I do because I enjoy them. I did this for our town. If people like it, come and visit. If they don’t, don’t, why worry?
