identify capacitors by their marking?

[myleftear]

Hi!
I once glimpsed an image which identified the various capacitor-brands (y'know, nichicon, elna etc.) by the design of the marking on the "lid"/cover...

some are rectangular crosses, others are wearing kind of a "right angle" etc...

Has somebody this picture at hand?
thanks!
