Postal Letter

How long will the post office keep unclaimed general delivery mail?

I sent a letter to my mom, 'general delivery' to a certain city in California, and I found out that she never picked it up. I didn't put a return address on it because I didn't want my dad to receive it if it were returned. I mailed it in 1965, late summer. Would the post office still have it? If so how would I claim it? Thanks for any help.

1. No, they wouldn't have it, and its been gone a long time. It was probably opened to check for an address but then it went on to its destiny. It was sent to the regional dead letter office and auctioned off
