- Originally known as the World Junior Welterweight Champion. The title bouts had a large share of notoriety thru Barney Ross, even gaining recognition in the brief resurgence with Tippy Larkin.
- Recognition has always been of debate in this era in this division depending on the basis of recognition. It has been said prior to the formation of the NYSAC, NBA, BBBoC, IBU and State controls all championships were based on individual and newspaper claims with 1919 being the ending year for this type of recognition. It also has been said that in the United States the recognition for championships were based on individual and newspaper claims for a longer period, even having newspaper decisions into at least the late 1920s. It also has been said that in this era the NBA at times announced recognition and withdrew recognition of championships at their convention and in newspapers.
