I have only bought/used 1 puck of Marvy soap (I have the big Marvy mug so I figured I should get a puck of soap) and I was not impressed with or excited about the total experience...so I feel no loss with the soap being discontinued. That said, I agree it is a sad sign of the times when old classics like Williams and Marvy are discontinued. I happen to love vintage soaps and purposefully seek out and buy vintage soaps of all kinds, even if I never intend to use them. One soap that I figure is much like Marvy is Surry, I don't know when they stopped productions and sales but Surry soap was often sold with a Surry branded brush and a mug. The Surry brush looks VERY cheesy, like it was intended to be a cheap add-on to make a "gift" package. The mugs I usually associate with Surry soap may not have actually been made by or sold by Surry (they are cool little mugs most often printed with classic cars on them). I am sure
@Spider can provide a much more complete list of vintage/discontinued soaps that may have once been popular ...but not popular enough to remain.
I am hesitant to say the demise of Williams and Marvy have much to do with the rise of the artisan soap makers. I would be more inclined to say the rise in artisan soaps may have help to keep these brands around longer by introducing more hype and popularity (and willingness to blind buy ANYTHING wet shaving related) to the market. I feel like the real reason these brands are no more is a more concerted effort from the bigger brands to dominate the wet shaving landscape in an attempt to profit from the rise in popularity among younger shavers. Maybe the Harry's, dollar shave and Jermy's razors play a part in all of this but I don't know what that part is.
