Piccadilly thin blades

Found this at a garage sale and I thought I would add it to the conversation.
Anyone seen these before?

Great graphics,maybe 1930's ?

Waits says that in 1929 Kampfe registered a trademark for Piccadilly blades: https://books.google.com/books?id=gOtQCAAAQBAJ&pg=PT82#v=onepage&q&f=false — and I see a 1929 advert in The Oil City Derrick of Pennsylvania:

MEN ONLY! THE QUESTION SOLVED AT LAST! AT LAST A RAZOR BLADE THAT IS A RAZOR BLADE PICCADILLY THE NEW SHEFFIELD PROCESS, GENUINE SWEDISH STEEL RAZOR BLADES for Ihe GEM, EVER READY, and GILLETTE RAZORS​

However this blade wrapper may not be from Kampfe, because that outfit was based in New Jersey and New York, and another image leads me to believe that the other side of that wrapper says "Piccadilly Blade Co. Chicago Ill." Also I found another 1929 reference to a "Piccadilly Blade Co., 1215 Filbert St., Philadelphia. Pa". Maybe it was just a popular name.

Gotta love the graphics on these old blades! I haven't seen that particular one before! Thanks for sharing.

More info... it says-
"made of watch spring steel 40% more flexible 33 1/3 thinner"
"Piccadilly Blade co.
Chicago Ill."
Made in USA

That's very cool art. For a while I was surfing vintage blade wrapper art quite a bit and I remember that art. I think I've seen a red version so I think they had a line of blades.

Had to bust out the razor blade book for this one.
Seriously:

Here's what it says

Nice Jason!
