Well all that effort at mapping Bruce Springsteen's studio album journey - from 'Greetings From Astbury Park, N.J.' (1973) through to 'Letter to You' 2020 - has been rewarded with a request from the Bruce Springsteen Archives (in Astbury Park) for a copy of the map to add to their massive collection.
For the first time in my life I am NOT looking forward to a new studio album from Bruce Springsteen .. his work to date has filled this particular tube map format.
Copies can be purchased here.
