It is one thing to see stamps individually in an album, but they sure seem more
interesting when they are on a cover. From what I understand, many mailers in the far east like to use a variety of colorful stamps rather than just one higher value, as they consider it artistic decoration rather than philatelic nature.
Now I feel bad using "Eternity stamps" except I get such a chuckle whenever I use one wondering how long Eternity is to the US Government. Maybe I will request that a pane or two be sent with me to the great beyond

CW, I agree they have some nice designs.
