Individually hand-drawn by award-winning illustrator Nirlay Kundu, these stunning watercolor cachets are quickly becoming collectors' items. Each envelope is handmade from acid-free, 100% cotton paper.

A software engineer by profession, Kundu learned to draw from his father. He developed a passion for stamp collecting at the age of five. After immigrating from India, he eventually combined his two passions in the creation of First Day Cover cachets. In 2005 he won the Rookie of the Year Award from the American Fist Day Cover Society for his Garbo cover.

"All my covers are unique in the sense that I draw each one of them individually and then hand colorize each one uniquely," says Kundu. "They are a labor of love. I use 100% cotton paper and cut my own envelopes."

In hot demand in Europe with a rapidly growing audience in America, each new Kundu cover is eagerly awaited. To see more Kundu covers available at County Stamp Center, click the post title. Order your favorite super hero covers today. Quick, to the Bat Cave! There's not a moment to lose!
