potential flag without coat of arms? (on erroneous flags used after 1934; from Världens huvudstäder)

See the source at [s9e36]. I have been working on this curious source and have found at least 15 flags whose specific representation in it is somehow noteworthy, including some unique, seemingly unexplainable errors.

The 2nd flag of the 4th row on the front cover shows the national flag of Costa Rica (and spells it "Costarica", while one would guess either "Kostarika" or "Costa Rica", based on how all other country names are spelt in this source): It is shown in 1:2 ratio, and this is relevant as this source, as said, shows different ratios for each flag, not all shoehorned to the same ratio. The official ratio of the national flag of Costa Rica was indeed 1:2 from 1906 to 1934, so this might have been a matter of showing a slightly outdated design, rather than an outright error. However, it’s not clear to me whether the plain striped flag, without the coat of arms, existed or not, in this 1:2 ratio of 1906-1934 period, as shown in the source.
