My RED-WHITE-BLUE wrapper is definitely a 1949 wrapper.
I'm not certain I understand your......"white red blue is undated 50 bowman" ?
Having collected "tons" of 1950 Bowman cards as a kid in 1950, I do not recall seeing any wrappers that year that were "undated".
All these wrappers were dated "1950" as shown in my scan here.
