This is a set of two Lionel Promo Collector Cards. The set includes 1 each of #1 of 2 and #2 of 2 from 1997.  I believe these two cards were the promotional cards sent to dealers, magazines, etc. to promote the Lionel series of collectible trading cards.  They are in very good condition.  Also included is one Lionel Preschool Little Choo Choo metal pin button. The pin button measures about 3-1/2" in diameter. See the photos for the condition of both the cards and the button.
