NOTE***:

LP Tae created and blessed KhunPaen Gumanthong both name-stamped back and plain back.

In the old days it's easy to find both plain back and name-stamped back items.

Cunning amulet "merchants" pushed the stamped-back items to much more higher price making more profit by selling them as "LP Tae's" while selling plain-back items as "LP Daeng's" (of Wat Thungkok, Suphanburi). 

Actually, LP Tae (B.E.2434-2524) and LP Daeng (B.E.2440-2510) were friends of each other. LP Daeng was 6 years junior to LP Tae and called LP Tae as "Luang Pee" (elder brother monk). Their temples are not faraway.   

Both LP Tae and LP Daeng often went into deep jungles to find woods for temple construction. 

LP Tae helped support LP Daeng by presenting a part of his plained-back amulets to LP Daeng to raise fund for temple construction. So, this was misunderstandably assumed that the plain-back items were created by LP Daeng.       
 

LP Tae is one of a few great Gurus who could create so efficacious GMT. LP Tae was a close disciple of LP Dha of Wat Paniang Taek, an old-day great Guru of NakonPathom Province.

In around B.E.2470, a few years after LP Dha's passing away, LP Tae went to learn higher Dhamma, magical knowledges and GMT making from LP Chaem of Wat Takong who was also a greatest Guru in the WWII period.

LP Tae created GMT of various kinds, such as holy powder table-size GMT, wearing wood-carved GMT, wearing ivory-tusk GMT, wearing baked clay GMT, wearing holy-powder GMT, etc.

GMT creation needs specific magical knowledge and high-leveled Smadhi to give birth and life to him.  

LP Tae passed away in B.E. 2524 at the age of 90.
