Jack writes on his Plate Faults Germany blog that while searching for stamps on the Internet, particularly Internet auctions, he wanted the pictures of the stamps to have more detail. A useful tool he often uses is "Virtual Magnifying Glass".
The software is a free and legal download at Source Force.
Jack says, "If you have installed the software you get the bottom right of your taskbar an icon. Right-click on the icon to set the magnification, etc., and then left-click on the icon to start your magnifying glass."
Also on Jack's blog (and shown above) is a picture of a Deutsche Post self-adhesive stamp dispenser. Interesting idea that USPS might consider for their next commemorative coil series such as the "Flags of Our Nation."
