Complete 15 volume set...Starting with the number 1 and the letter A, and ending with the number 15 and the letters X, Y and Z. Beautiful hardcovers with illustrations throughout. Wonderful learning tool.
Does anyone else remember getting these books at the grocery store? They'd put out a new volume every week until they got through the series. To this day, I kick myself for not hanging onto my set. I was able to pick up Volume 1 at a garage sale years ago, but that's all I have now. Must check eBay to see if I can get the rest.
