Stela 33 was the first erected and served as Itzam Kʼan Ahk I's ascension monument. Carved on December 1, 642, this stela depicts the "ajaw" sitting on an elevated cushion; a "plain band" is wrapped around his chest, which Clancy argues represents his being "bound to office". The leader is uniquely shown in profile, looking towards his right at a woman who is offering him "royal regalia". This woman is usually considered to be his mother, although Mark Pitts notes that she could be his wife. O'Neil favors the former argument and writes that Itzam Kʼan Ahk I's mother was likely featured on the stela because she served for a time as her son's regent and was thus politically important.
