In Marvel's Daredevil there have been scenes where a 48-star US flag is shown (instead of the 50-star flag which in the real world has been in use since the late 1950s).
Here's an example from season 2, episode 7 of Daredevil, the 48-star flag is on the wall behind Foggy Nelson & Karen page:
Why is this flag used? Is this consistent with the rest of the MCU? Marvel-related films & TV normally seem to have a very high attention to detail, so it seems this is in there for some specific reason - even if it could be a somewhat secondary detail.
