Latvian Post will issue a souvenir sheet commem-orating Struve’s Geodetic Arc. The May 5, 2011 issue, shown below, contains two single stamps, a 35 and 55 lat denomin-ations. A marker monument is shown in the 35 lat stamp. The center background of the sheet shows a theodolite possibly used for the measurements, and on the left of the sheet is an observation tower. What appears to be a photograph of Struve along with a similar survey instrument is shown on the 55 lat stamp. There are two measurement points in Latvia.
