Entitled "The Rookies," this 56-card set includes the top 55 rookies of 1986 plus an unnumbered checklist. The cards are similar in format to the 1986 Donruss regular issue, except that the borders are green rather than blue. Several of the rookies who had cards in the regular 1986 Donruss set appear again in "The Rookies" set. The sets, which were only available through hobby dealers came in a specially designed box. - 2006 Standard Catalog of Baseball Cards, 15tht Edition.
