Catalog numbers for MARY CASSATT 37c American Treasures Issue of 2003?

Can someone provide me with the Scott and/or the Krause-Minkus catalog
numbers for the MARY CASSATT 37c American Treasures Issue of 2003?
There are four stamps in a block repeated five times on one
self-adhesive strip.

My catalog is a few years old and does not cover current issues.

Thanks very much.
