The Nov/Dec issue of Bible Study Magazine has the following:

Brannan, Rick with John D. Barry, “The New Testament Didn’t Drop Out of Heaven” Bible Study Magazine 2, no. 1 (November/December 2009): 30-31.

It’s in the “What They Don’t Teach You In Church” column and is a very short article (heavy on graphics) that introduces the concept of NT manuscripts and their numbers, particularly in comparison to available MSS of other corpora.

If you already have Logos 4, you can already see the primary graphic in the Logos Bible Software Infographics resource. [NB: Link is to a video on YouTube displaying the infographics resource]
