Microprinting On Recent Definitives

Does anyone know...is there a recourse somewhere that shows me where to find various microprintings on recent definitive US stamps? Even with a magnifying glass, they are proving hard to spot. Currently I'm looking at #'s 4559, 4561, and 4563...Lady Liberty issues from 2011. Can't find them anywhere. Help!

The Scott US Specialized points out the locations of the microprinting. But even knowing where to look, they can be hard to spot. For Lady Liberty, look in her hair on the right hand side of the stamp at about the level of her eyes. For the flag, look at the very bottom of the bottommost red stripe, just past the area where the flag curls over itself.
Added: My magnifying glass was not sufficient ... had to use my loupe magnifier to locate these!

Thanks! Honestly, I'm usually just able to pick it out under a bright light and without a magnifier. I can't actually read it, but I can see it's there. This one just eluded me. I need a loupe.

The microprinting is easier to detect on the Ashton Potter stamps for this issue. Knowing where to look, I can see that it's present with a magnifying glass for these. Not so with the other printers. This, of course, may have something to do with my aging eyes & cataracts.
