A cheap brand of "all-purpose" smoking tobacco - one of the earliest packaged, branded pipe tobaccos in the U.S. - with the slogan "a cargo of contentment in the bowl of any pipe." A long-standing joke involving the product's name asserts that it is named "half and half" because it is comprised of "half horseshit and half bullshit" (in reality, the mixture is half "bright" and half "burley" tobaccos). Some old-timers speculate that the half and half joke may have given rise to the novelty "horseshit cigarettes" sold in the U.S. in the 1920s-30s (not real horseshit), which featured the slogans "not a fart in a carload," and "try one, you mooching bastard."

Half and half is still sold at most retail outlets carrying tobacco products.
"Cargo of contentment," my piles - half and half is harsh and bitter.
