TheJewelOfJool's request - may have taken the 70s - 90s theme a bit far, whoops! I did a bit of research and a ton of airlines in that era had lines going from front to back, and in the 90s they were making the lines go from the front to the top of the tail (as opposed to just front to back of fuselage). I made 2 versions of the tail, I wasn't sure which looked better. I'll DM you the version with a faded watermark.
