The Allies Flags Puzzle

Circa 1920's?
(left / right bottom: 2.15" x 2.7" x 1" box and 5 paper covered 3/4" wood cubes;
right top: 1.3" x 4.2" x 1" box and and same cubes as puzzle on left)

Similar in name and theme to the Allies Flag Puzzle, cubes have flags from World War I (U.S., British, Red Cross, Russian, Republic Of China). Like the Instant Insanity puzzle, the object is to arrange the five cubes in a line so that each side has no duplicate flags. Here is a solution and its corresponding graph (constructed in the same way as for Instant Insanity):



cycle 1: US - 1 - Russian - 4 - British - 3 - Red Cross - 2 - Republic Of China - 5 - US
cycle 2: US - 2 - Russian - 3 - British - 4 - Red Cross - 4 - Republic Of China - 1 - US
