One of my favorite things about Southwest Airlines is their use of special schemes over the years. It all started with 737-3H4 N334SW when it was painted into a special "Shamu" scheme on 5/23/1988 in recognition of Southwest's partnership with Sea World.
I have a photo of N334SW in Shamu scheme in canyon blue paint:

Following on May 10, 1990 was 737-5H4 N507SW dubbed "Shamu II"

The first of the "State Flags" special schemes was on 11/7/1990. Lone Star One, honoring Southwest's home state of Texas...was painted on 737-3H4 N352SW:

After N352SW was retired on 5/17/2016, the scheme was applied on 737-7H4 N931WN on 7/15/2016:

The next special scheme was introduced on 6/6/1996 in honor of Southwest's 25th anniversary, bare metal "Silver One" was applied on 737-3H4 N629SW:![Southwest B737-3H4 N629SW L.jpg Southwest B737-3H4 N629SW L.jpg](https://modelairlinerforum.com/data/attachments/0/933-9b83bd4c0d0536c4e4bd07209086c322.jpg)
N629SW was later repainted into a silver paint due to maintenance costs..and it was eventually painted in a gray paint with the Canyon Blue tail. It was retired on 8/14/2017
continued in part 2.
