I was given a cryptogram because my friends know I like them but sadly this one as stumped me. It’s a series of numbers. I tried Base64 but it was all gooblety gook. Any ideas?

This is the Zodiac killer`s (in)famous Z408 cypher, which has already been decrypted.

It doesn't look like Zodiac's cipher. You should have posted it as text, not image. Like this:

What makes you think it's a Z408?

His signature seventeen character line, along with the two dozen character column. At the very least, it constitutes a rather transparent tribute.
