This and similar covers that will be offered in weeks to come are from the estate of philatelist Kevin Seward of San Pedro , California who past away in February, 2021. Mr. Seward, a close friend of Walter Crosby, amassed a huge collection of Crosby works including these by artist Raleigh D. Newton, also of San Pedro. The inside stuffer states that they are by "Improved Crosby Naval Cover Service, ORIGINAL CROSBY COVER ALBUM MFG, P.O. BOX 602, SAN PEDRO, CALIF.". I was fortunate to become aware of these covers earlier on and was fortunately able to acquire almost the complete collection of these R. Newton Hand Painted covers. Philatelist dealer, Joel Weinstein, believes that Newton was an apprentice artist for Crosby and believes his covers are all one-of-a-kind because he has never seen any others.
