First Learning Company is recalling both the Big Wood Blocks and Jumbo Wooden Train Sets.
The Consumer Product Safety Commission says the surface paint on some pieces contain an excessive level of lead.
Lead can be toxic in young children.
The sets were sold in Christmas Tree Shops from October 2006 through November 2007.
The Big Wooden Learning Blocks styles 7210, 7211 and Jumbo Wood Train Sets style 13275A are included in the recall.
Return to any Christmas Tree Shop for a refund.
