I recently came across a couple of bands that have multiples logo's. (Used in the past & present)
What should be done regarding this? Keep the new one's or make a collage of all past & previous logo's? Some bands also have multiple logo's that are used in different medium's. Different logo's for flyers, shows.

I am confused regarding this. Can anyone help me out.

It was decided a while ago that there should only be one logo used for each band - their most recent one if active, or the one that they are most known for if not. There used to be a lot more bands with more than one logo, but they've been getting fixed as people come across them. You can fix them if you're able to, or put in a report, though it's not a very high priority.

Ok Sir. Point noted. Thank you for your time.
