This A388 Livery is inspired by the early teasers for the Lufthansa 100-Year Anniversary Liveries.
Since details are only available for the B789 yet, I left some of the detail like name in registration out for now. 
Feel free to let me know if you know more details, with sources.

Great Thanks to rayq167 for sharing his 100 Year stickes

Installation:

Copy folder from inside the zip file into your MSFS community directory.

Also see: Installing Addons in Microsoft Flight Simulator

I recommend MSFS Addon Linker

FAQ:

- Addon causes errors on extraction

Windows has a legacy limitation to a maximum path length of 256 characters. This often raises problems while extracting.

1. Remove legacy path length limitation using this guide (recommended):

2. Option shorten path (dirty)
shorten path, either by renaming the addon base directory or changing the MSFS community path

3. Move community directory
you can move your community packages directory so that the full install path is not that long anymore.

4. Use Addon Manager

Addon linker allows you to install all addons to a directory and load (link) them into the community directory dynamically.

- There are differences to the real livery, can you adapt it?

This Addon was created very early when onl y promotional material available. Adapting mayor alignments would mean to start over from scratch. I may do a v2.0 but it is not planned for the near future. I expect there to be a new version for the Inibuilds A380 soon anyway
