Larry Walker - 1998 Circa Thunder Thunder Boomer insert
Fleer/Skybox produced the Circa brand of cards from 1996 through 1998 (they were renamed Circa Thunder in 1998). This is an insert from the 1998 set. The Circa cards base sets featured unconventional backgrounds with very colorful abstract designs. The inserts were also unconventional often featuring materials not common in baseball cards. This card is a composite with white card stock on the front and clear acetate on the back. The card stock is cut away around the player allowing the blue clouds on the acetate to show through. All of the text on the front is in red foil. The card commemorates Walker's 1997 season when his slugging percentage was 0.700 and he hit an NL leading 49 home runs. I purchased this on eBay for $1.50 in December 2007. Beckett lists the card at $6.00.
