Can you tell the difference from the color? I've seen pictures of BB shave soap where the soap is blue. Mine is kind of a tan color.
the reformulated ones have "penhaligon's" imprinted on the soap instead of the soap name
Great. Does anyone have a similar picture of the BB showing the name and Penhaligon's? I'd sure love to see those two. Also, is the blue BB just a new color for the reformulated BB, or was it changed to blue when it was reformulated. If the latter, then my tan one would be the older version. As someone already mentioned, it's been used a little and all writing is now gone.
Here is a shot of the tallow formulation soap (sorry it couldn't be bigger; its someone's avatar):
