I’m not able to attend Destination Star Trek Birmingham this year unfortunately.
However, the internet has been flooded with photos of Admiral Jean-Luc Picard’s uniform which is on display for the first time anywhere!
Photos below. As you can see its a updated version of the Admiral’s uniform from TNG but, to my eye at least, borrows also from Star Trek Online.
Destination Star Trek is on all weekend and tickets are still available I believe. Check here for more information.
