Mr Boobalan, a school teacher in Chennai, has turned into a bookseller to sustain his livelihood, which was affected by the Covid-19 pandemic.
He arranges books on the top of his car and sells them on the roadside in the south Indian city.
The 40-year-old, who used to teach in a private school for 12 years, has been selling fiction and non-fiction books this way for the past six months.
Following the reopening of schools in Tamil Nadu this month, with the easing of Covid-19 restrictions, he started to teach again in a private school.
But in the evenings he continues to sell books to support his family.
