Boyd Holbrook adresse

[Fedi2210]

First things first, since 2012 I am a big fan of Boyd Holbrook as he acted in "Hatfields & McCoys" and I want to send an autograph request to him. The only adresse I can find is

Boyd Holbrook
Imprint PR
953 N Sycamore Avenue
Suite 750
Los Angeles, CA 90038
USA

which is ok but in the internet I just find the adresse but nothing about this company which makes me kind of pensive not least because I live in Germany and a letter from here to the USA (and back) costs about 10$. I do not have a problem with the price when it is sure that the letter reaches him or his management.

So i wanted to ask if somebody has an advice or maybe even sent something to exactly this adresse. Or is there a better adresse to try it out? Should I just try it? I do not have that much experience in collecting autographs.

Thank you in advance
