About Royal Retro:  US company based in Portland, OR. Their throwback line includes limited runs of jerseys of defunct teams from the past. They focus on creating small runs of custom apparel in authentic style that are patterned after the original jerseys of days gone by. The company was originally founded in 2015 as 503 Sports and inspired by the Portland Mavericks.

This jersey was discovered in an estate with other jerseys made by Royal Retro with their tag, so we assume all were made in the same place and era.
