for gibson j45

What kind of guitar strings should I buy for my Gibson J45?
I have a 1962 Gibson J45 that belonged to my grandpa and I’ve decided I’d like to start playing. The strings on the guitar now are old and I’d like to buy new ones, but I’m not sure what kind to buy. Help please?
try a set of martins. go to a guitar shop and ask for them. nice vintage guitar!
