10 Latu

Latvia's interwar Treasury notes were produced under tight fiscal constraints following the lats' stabilization in 1922, and the 10 Latu went through an unusually long printing life — the number of signature combinations on this single type reflects successive ministerial changes across more than a decade of continuous issue from a single base design. Bradbury, Wilkinson's engraved work held up well enough that no redesign was ever commissioned.

Series progression from A through U, with overlapping signature pairs at the transition points, occasionally creates attribution confusion. The Skujenieks pairing is the most historically notable — Marģers Skujenieks was a prominent statistician and minister whose career ended with Soviet occupation in 1940.
