I have hundreds of Mack Bolan/ Stony Man/ The Executioner books and will be putting these up on eBay over the next few weeks. The books range from acceptable to excellent condition; some may have pen inside and/or library stamps/stickers, etc - please do ask if you require any additional information before buying. 

If you are looking for a set bundle or specific titles, pop me a message and I'll see what I can do.
