Lost cherished 1960s comic book series left on a living room coffee table at a friend's house in Humboldt County.

I lost my cherished 1960s comic book series while visiting a friend's house in Humboldt County. I had set them down on the living room coffee table and forgot to take them when I left. They have some nostalgic value to me as I collected them during my childhood. Each issue is a classic and has significant personal meaning. Please help me get them back!
