St. Vincent & the Grenadines are a chain of islands in the southern Caribbean (also known as the Windward Islands). The main island of St. Vincent is about 11 miles wide by 18 miles long. The population of St. Vincent along with the Grenadines islands is approx. 120,000.
The map stamps from St. Vincent above will give you an idea of the location, size and shape of St. Vincent. St. Vincent is a lush tropical island and is probably the most unspoiled of all Caribbean islands (there are no mega resorts here, just a few smaller hotels and inns). If you want to really get away from it, then I would recommend a vacation on St. Vincent and the Grenadines (I was fortunate enough to visit there for a week in early 1993 and also in the Spring of 2007 as part of the British Caribbean Philatelic Study Group Annual Meeting held there).
Back in the early 1900's, there was no radio, television or internet. People had to communicate by writing. Picture postcards (or "view cards" as some people call them) as we know them today got their start in the late 1800's, but the postcard collecting craze was very high from the early 1900's to about 1920. This was a great way for people to see and learn about other parts of the world.
There were several hundred St. Vincent postcards issued in the early 1900's, but they are very difficult to find (compared to the other islands in the Caribbean). Unused cards are going to be the most common ones, while cards that have been postally used will sometimes command a premium price, as they will then also be deemed "postal history".
Note: "Saint Vincent" is not to be confused with "Sao Vicente CV". The "CV" stands for "Cabo Verde" (Cape Verde), which is a former Portugese colony that is situated in the Atlantic Ocean about 500 miles west of Senegal (Africa), while St. Vincent and the Grenadines are a former British colony in the Caribbean. Sao Vicente is one of several islands that comprise Cape Verde. For more information about Sao Vicente, visit: http://www.caboverde.com/ilhas/ysvic-it.htm
