How can you tell if your old vinyl lp is mfsl?

To determine if your old vinyl LP is a Mobile Fidelity Sound Lab (MFSL) release, check for specific markings on the album cover or label. Look for the "MFSL" logo, which is often found on the front cover or back cover, and verify if it includes a catalog number that starts with "MFSL." Additionally, you can examine the record itself; MFSL pressings typically have a high-quality, glossy finish and may feature specific mastering techniques noted on the label. If you're unsure, you can also consult online databases or collector communities for reference.
