Seller: x2safet (4,345) 100%, Location: Lake Forest, Illinois, Ships to: US, Item: 132799724618 Fill those empty spaces in your US Air Mail section from my inventory. $2 gets you $1 in face value from the stamps pictured. Inventory ranges from C30 to C140 or so with some gaps. See pics although I have run out of C27-29 and some other pictured issues. If your wish list doesn't add up to a round dollar number, simply double the face value & make an offer for that amount. (You may need to buy multiple lots to accomplish this - for example, I'll sell you $1.50 of face value for $3 but you'd need to make an offer for two lots at $1.50 each.) Contact me with questions and/or to check availability before ordering. I will do my best to keep all the stamps pictured in stock. FREE S/H in continental US.
