How to write the address???

[FCB_Phil]

I am very unsure how to write the address, because I sent 3 times (!) to Kevin Costner performing in Germany (around 3-4 days before the concert started) and recived nothing while other recived their pictures back signed. So what did I wrong???
I wrote the address like that (example):

Kevin Costner
E-Werk Köln
....... (address of the E-Werk)

Should I better put the date of the concert on the envelope, or what???

Thank you very much for your help in advance!

Yours sincerely,

No, there's nothing wrong with what you wrote. But I do suppose it'll help to write "Hold for (date)" or something like that on your envelope. You also might want to try sending it a week before the concert starts. 3-4 days may be cutting it close, and it might not make it on time. Hope you're successful this time
