it is a marshall logo on a 1960 cab. that is the only thing i have of marshall and i want to take it off. i wouldnt really call it a marshall anyway. i got the cab unloaded and put tubbies in it. i would call it a built by marshall tubby cab.
Most Marshall Logo's have 5 pins with either fasteners, heat staking or glue (not stock) on the back. You will need to remove one or two of the speakers to get to the pins on the back of the logo. If there are fasteners, just pull them off. If the pins are glued or heat staked, you may need to clip them off from the back.
