You are purchasing a used attached se-tenent set of 4, #2620-23 First Voyage of Christopher Columbus Issue,  29 cent, off paper.  The scan is a sample.  The stamps include:  Seeking Queen Isabella's Support, Crossing The Atlantic, Approaching Land, Coming Ashore.  Shipping is $.63 within the United States, outside the United States is $1.45.  I do combine winning bids to save on shipping costs, I only make adjustments for weight changes so you can sometimes put several together and it has no impact on shipping costs.  Thanks!
