How do you do last but not least in rebus?

To represent "last but not least" in rebus form, you could use symbols and Words that convey the phrase. For example, you might show the Word "last" next to a picture of a person standing at the end of a line or a final item, followed by a "not" symbol (like a crossed-out circle) and then the Word "least" or a small item. This visually communicates the idea of something being last but still important.
