Vintage Vikings Tag Question

[69Vikes]

Does anyone know if Powers was a jersey supplier for the Vikings ever? I am not too familiar with this tagging

The next one I see that is genuine will be the first. Having said that, though, I am not sure who supplied the Vikes prior to the late 1960s. It's possible they may have snuck in there in the early-mid 60s. The tag looks different from any Powers tag I'm familiar with from the 1970s/80s, so don't give up the ship just yet! Anyone else able to chime in?
