Listed in Scotts Specialized Catalogue as S1 War savings stamp the 10¢ rose you have issued November 30 1954. The 1954-57 series also included a 25¢ blue green, 50¢ ultramarine and $1 gray black.
Here's the 25¢ stamp

They were collected in a booklet.
Here are scans of inside pages of the book in my collection, which also includes the 1941 Postal savings stamp that Rod's page holds.

Here's the back cover of the book. For some reason I've not scanned the front of the booklet. I'll have to remedy that.
