A confusing description created by Beckett years ago led many people to believe that this was a 20-card set. Review of other sources from the time of the set's release as well as evidence presented in this conversation:

indicate that the 5 'Legends' cards were never part of the Rudy's Farm set, they were only available from the R.B. Rice promotion. The R.B. Rice set is listed here:

I received a random box of cards to sort through and have over 100 unopened packs of these. Each pack has three cards, and you can see what is on top and bottom. I'm not a racing collector at all, so let me know if you're interested in buying or trading for sports cards (mostly baseball).

I've opened about 30 packs and have multiple complete sets built (excluding the 5 mail in "legends" cards). Or I have about 100 unopened packs remaining. Whatever you prefer.
