Snatch -- my recollection is that Arrco was sold to (I think) U.S. Playing Card Co. who then issued inferior cards with that name (by inferior, I mean like Hoyle's). I think those are the ones available from Kardwell, and I'd avoid them.
The original Arrco Casino Clubs and the other quality whose name escapes me right now are the only ones you might be interested in. But even in this case, the general unavalability and thus unusal look of the cards would make them impractical, I'd say, for actual use with spectators.
In their heyday they were certainly the cards of choice for many serious cardicians.
Richard K. -- what do have to say?
