Luang Pu Khampan Khosàpanyo
Also known as the Official First Batch Rian in 2519 where Luang Pu didn't allow His face to be on it. These were the proper practices back then.
It features That Mahachai a side and That Phanom on the other.
Now this Rian had a miracle reported by a devotee and happened in Singapore back then. It is featured in Luang Pu's Official Book. This particular devotee was a construction worker in Singapore wearing this Rian. An accident happened and he fell from the 6th story of his worksite and escaped unscathed.
