Found elsewhere on the web (can't post a link to another forum):

"Barbara Brackman's Encyclopedia of Pieced Quilt Patterns says that Card Trick was designed in the 1970s by Gutcheon in McCall's. Beth and Jeffrey Gutcheon were quilt book authors back then (and might still be for all I know) and McCall's magazine has been publishing all kinds of patterns and books forever."

and

"Jeff Gutcheon did design the card trick block back in the 70's. He and Beth (who also wrote The Perfect patchwork Primer, and is now a distinguished and successful fiction writer) were WAY ahead of their time. Their Quilt Design Workbook was by far the most innovative and influential book on contemporary quilting. Things like chain piecing, and new designs such as card trick and many other features were considered great leaps of quilting in a day where all you could find were ditsy calicos. The book still holds up today. Get a hold of a copy (library, ebay, quilt guild library) and you will be quite amazed. They also feature the work of other celebrity quilters of the 70's such as Molly Upton."

ETA: Just FYI, the Faux Card Trick block was designed by Anita Grossman Solomon. She confirms that Gutcheon designed Card Trick.
