It shows Victorian homes in Steiner Street in San Francisco, as seen from Alamo Park. I have a few postcards of these houses but I don't think I'll ever get tired of them. They look so pretty and colourful, and I love the contrast with the city seen in the background.
These houses are also called "Painted Ladies". It's a term used for Victorian and Edwardian houses and buildings painted in three or more colors that embellish or enhance their architectural details. The term was first used for San Francisco Victorian houses by writers Elizabeth Pomada and Michael Larsen in their 1978 book Painted Ladies - San Francisco's Resplendent Victorians. Since then the term has also been used to describe groups of colorful Victorian houses in other American cities, such as the Charles Village neighborhood in Baltimore City, Lafayette Square in St. Louis, the greater San Francisco and New Orleans areas, Columbia-Tusculum in Cincinnati and the city of Cape May, New Jersey.
One of the best-known groups of "Painted Ladies" is the row of Victorian houses at 710–720 Steiner Street (as seen on this postcard!), across from Alamo Square park, in San Francisco. It is sometimes known as "Postcard Row." The houses were built between 1892 and 1896 by developer Matthew Kavanaugh, who lived next door in the 1892 mansion at 722 Steiner Street. This block appears very frequently in media and mass-market photographs of the city and its tourist attractions and have appeared in an estimated 70 movies, TV programs, and ads, including in the opening credits of the television series Full House.
I think everyone who has received postcards from the USA must know this stamp.. :p It shows the Grand Teton National Park in Wyoming, and was issued in 2009.
