This fight likely took place in the mid to late '80s, around the time Samart made the transition to English boxing. He's in southpaw stance here, a change he adopted in every one of his English boxing fights.
Samart Payakaroon I've introduced before. The short of it is, if you ask anyone in Thai Muay Thai to name the greatest fighter of all time, Samart will likely be named. He was at his prime in the '80s and moved to English boxing in 1986 after winning the Lumpini 126 lb featherweight.
Jarontheong Kiatbanchong is one of the top fighters in Samart's era, what's generally considered the Golden Age of Muay Thai, from the '80s to '90s, when interest in the sport was at a peak. He's also shortlisted one of the greatest fighters of Muay Thai, having beaten a number of champions like Chamuekpet Hapalang, Langsuang Panyupathum, and Panumtuanlek Hapalang.
Samart is in red, Jaroenthong blue.
