Here is a letter I obtained from the "Transactions, The Supreme Council 33º 1975" Masonic book on page 48. This letter is addressed to the then current Sovereign Grand Commander of Scottish Rite Masonry offering praise for his antichrist book. At the bottom of the letter shown clearly underneath Peale's signature is the 33º Symbol stating that Norman has received the 33rd Degree of Freemasonry.
Here Norman is listed in the Masonic reference book '10,00 Famous Freemasons'. When this book was published Norman was only a 32nd Degree Freemason.
