Tee has been painting for 16 years but has been a full-time artist since losing his job during lockdown.
The 34-year-old is part of the We Love Merthyr, external project, which aims to regenerate the town.
Merthyr Tydfil council wanted the project to “bring a bit of colour” to the area, according to Tee.
“They also wanted it to involve the people of Merthyr in the creation of the artwork,” he said.
Tee managed to round up more than 30 locals to help him finish the mural across a weekend.
“We had three-year-olds, all the way up to grandparents joining in,” he said.
“The majority of it was done by children between the ages of 10 and 18.”
