They seemingly ignore that era in franchise history. It’s not like they do it because of futility. The Twins acknowledge their Senators roots.

Honestly, they should bring back the throwbacks every time they play the St Louis Cardinals on the road.

I've seen franchises keep 2 sets of records. One set for after a team moves and/or changes its name. And another set of records for the all time history of the franchise. This can get confusing for clubs that existed before 1900 but it should be possible for any franchise that started after 1900, I would think.

Think about how long ago the relocation from St Louis to Baltimore was. That move happened in the early 1950s. There’s not exactly a lot of baseball fans alive who grew up with the Browns in St Louis to be nostalgic about it.

For a franchise like the Montreal Expos, whose move is much more recent, there are far more folks watching baseball who grew up when there was a team there.

On the other hand, they are probably missing a merchandising opportunity by not bringing out Browns throwbacks every time they play the Cardinals in interleague play.
