First of all, you will need to re-size the pic, then post it in the "Vintage Cymbals" section, that way the cymbal guys can have at it. If you have some ashes handy, rub them into the logo, and then you can simply rinse them out. That way you don't lose any patina or risk some lowering of value. Ashes is the only way I know of to bring out the logos on faintly embossed cymbals.

NEVER use a scrubber or other cleaners on your cymbals unless you really know what you are doing as small surface swirls and scratches can and will de-value your cymbals.
