How the Mail is Delivered in the Netherworld
Thinking about, as I sketch out the back of Netherworld Post's shipping manifest, the very first graphic design books I ever bought (2003? 2004? Somewhere around there) were how to squeeze every production budget dime to do Something Cool and Scott McCloud's Understanding Comics
Flipping paper over and printing black ink on the back is (nearly) free if you're printing at home (I will + most folks do). If you are making your shipping receipts/manifests fancy (WHY, get a LASER PRINTER), professional printers can do this pretty cheaply too
In my instance, the reverse side is going to be a guide on how the Netherworld Post Office delivers mail to ghosts, goblins, mermaids, witches, and monsters of all kind.
I'm also going to spotlight individual letter carriers over time, so you can get to know some great creepers
