I smell a fake. Paper was in existence and used for a thousand years before 1815 and blackboards were never really an alternative AFAIK.

Considering blackboards, I went to a school built around 1970 when
somebody decided to make the blackboards light brown, almost the same
color as white chalk.

in the 1990's my adult sister discovered Armor All for her car and went a little overboard and Armor Alled the brake pedal! It LOOKED great but was slippery! She learned never to do THAT again.

Armor All on a motorcycle saddle isn't the best idea in the world either.
