I'm not sure any of the following necessarily require crediting, since I think they are all as old as cards. The origins may have been forgotten. But in any case, I'm about to start sending out a document describing an effect that touches on these methods, so if the origins are known I'd like to mention it.

If anyone has any Info, I'd appreciate it.

OBER EBOR: (Odd Black Even Red, Even Black Odd red)

ONE WAY BACKS: (Asymetrical Back Designs)

ONE WAY FACES: (Asymetrical Face Designs)

FLATS AND ROUNDS: (Flat or Pointed Tops of Index Numbers Vs Round Tops)

Like I say, I'm sure these fall outside the scope of what should be credited.

OBER EBOR: (Odd Black Even Red, Even Black Odd red)

I can only think of one printed source for this principle. That's Don Alan's book In a Class by Himself. However, Don Alan did not originate this idea. I know where he got it from. I'm not going to discuss it here, but if you send me an e-mail at curator@cupsandballsmuseum.com with OBER-EBOR in the subject line, I'll tell you the whole dirty story about how "The Great Innovator" Don Alan got hold of this non-credited idea.

Bill, isn't the principal behind OBER EBOR related to an old Charles Jordan effect? Or am I thinking of something else?

Do you have a reference?

I've been trying to find it all evening, it's driving me nuts LOL

I found what I was thinking of, but after re-reading it I think it is probably only obliquely connected, It's "Improved Marvelous Prediction" as it appears in the Encyclopedia of Card Tricks.
