This series, known as "Albatros dentados," holds significant value due to several unique factors. The series was issued on June 25, 1928, and was designed by the architect Juan Antonio Scasso, printed by the National Printing Press of Montevideo using a lithographic system on sheets of 25 stamps with a watermark and perforation of 11. One intriguing aspect is that Scasso, the architect behind these stamps, also designed and constructed the Centenario Stadium, explicitly built for the first FIFA World Cup. Scasso was responsible for the municipality's green areas and was heavily influenced by Art Deco.

Regarding the stamps, they were issued in quantities ranging from 30,000 to 10,000, but many were incinerated. Among the most significant values:

• 1p - 10,000 printed, 5511 incinerated, remaining 4449
• 1.14p - 20,000 printed, 17825 incinerated, remaining 2175
• 1.52p - 20,000 printed, 18094 incinerated, remaining 1906
• 1.90p - 10,000 printed, 8045 incinerated, remaining 1995
• 3.80p - 10,000 printed, 8733 incinerated, remaining 1267

This information suggests that fewer than 1,300 complete sets may exist, making this series exceptionally scarce. Additionally, its thematic elements of birds and the 1930 FIFA World Cup enhance its collectible appeal.
