Here's part 1 of an introduction, it is primarily about Boss Mortician...
Boss Mortician rose to success post-WWII, offering mid-quality funeral services at mostly affordable prices. His speciality was a range of caskets built to resemble the fallen trunks of grand oaks, complete with knots and broken branches, these caskets would be lowered into the ground by a small crane owned and operated by Boss Mortician. The tree casket range was discontinued in 1963, due in part to the flammability of the materials used.
