Resolve the issue regarding the brand's foundation year edit

There is a conflicting claim on the foundation year. Based on the book Superbrands Philippines, Volume 4 (2005-2006), pages 72 and 73 (http://superbrands.s3.amazonaws.com/AAA%20MASTER%202%20PAGE%20PDF%20Case%20Studies/Philippines/Philippines%20Edition%204/Philippines%20Edition%204%20Nagaraya.pdf) containing the detailed history of the brand, which I presume was written with the cooperation of the company, states that the brand was established in 1968. The Nagaraya website however states 1967. iamdumdum (talk) 10:07 AM, 15 May 2022 (UTC)
