Before the council strips of today were used, most scouts wore a simple Red & White strip with the name of their community and a separate Red & White strip with their state.
Professionals at the time wore a single strip with the entire council name and are referred to as Half Strips
Before this, they were the same thing except for Khaki & Red strips
These transitioned into single Red & White Council Strips
There are many varieties of these strips as councils changed names and merged over the years. This category of Boy Scout collecting has really picked up steam in the last several years with some strips selling for over $1000.
There are also varieties for Sea Scouts which are White and Blue and Air Scouts which are Dark Blue on Light Blue.
