An advertisement from 1852: Pianos and pencils getting nearly identical billing (let’s hope they weren’t nearly the same price). It’s interesting though that a reseller would count pencils among its high-quality items; in this instance the pencils in question are A.W. Faber’s Polygrades (more on those later).
After seeing “piano fortes” I couldn’t help thinking that pianos forte would read better, but that would be due to the influence of “piano” in modern usage. In other words, they sell “soft louds” not softs loud.
+1 for “&C.”
