Good Dodger themed gift for a father/son?

Hello! I'm a Giants fan, but I'm really excited to watch some Giants/ Dodgers games this year! They are the most thrilling games to watch all season! I'm sure you guys are sick of hearing it, but fuck, are we jealous of Kershaw.

Anyway, I'm looking to get a gift for a friend who is a big Dodger fan. He is in his 40's and has a 2/3 year old who he takes to Dodger games all the time. He is a die hard fan, truly. Anyway, aside from like a father/son t-shirt, are there any other gift ideas for them? I figured something he won't outgrow, perhaps something he could keep for a long time. I'm also not looking to spend an insane amount of money. Let's cap it at 50 bucks. Any help would be greatly appreciated!
