This elephant drawing with what I take for a symbol, letter, or number, is from a book published in Hanoi in 1936 by Institut Bouddhique Vientane. Appears to be one of 30 books produced at the time.
I altered the colors from the original as part of my ongoing project and experiment in photocolorization.
If anyone knows more about this symbol, I would appreciate an e-mail or comment.
Many thanks, Andrea
