Mrs. Carroll Wilhelm lived in Westfield, a town of Union County in northeast New Jersey.

Westfield is about 16 miles southwest of Manhattan.

In February of 1934, Mrs, Wilhelm received a postcard from Aunt Lillie and Evelyn.

Aunt Lillie and Evelyn were in Miami Beach, possibly at the Roney Plaza Hotel.

The Roney Plaza Hotel was the first of the luxurious hotels built on Miami Beach.

Erected in 1925, an designed by the architect of the Waldorf-Astoria in New York, the hotel was demolished (to erect condominiums) in 1968.

This description is from the website of the Miami Design Preservation League, which I cannot link to this story:

“The Roney Plaza Hotel, considered the very first of many monumental beachfront resorts, was once located at Collins Avenue and 23rd Street. It was built by New Jersey lawyer Newton Baker Taylor Roney in 1925 after having purchased the land site from John Collins’ Miami Beach Improvement Company for $2,500,000. It was one of Roney’s most famous developments in Miami Beach, with the other being the Spanish Village on Española Way. The luxury nine-story hotel was designed by Schultze and Weaver, a New York architectural firm which was also responsible for the Waldorf-Astoria Hotel in Manhattan, The Freedom Tower in Downtown Miami, and The Biltmore Hotel in Coral Gables. The firm drew inspiration from the famous Giralda Tower in Seville, Spain for the design of their Florida properties, including the Roney Plaza.”

The face of the postcard from Aunt Lillie and Evelyn shows “Tea Dance at the Roney Plaza Hotel”.

The linen-style postcard was published by the E. C. Kropp Company of Milwaukee.

On the reverse. Aunt Lillie writes, “This is the place to enjoy the sunshine and escape the cold”.

The travelers send Love to Mrs. Wilhelm.

One hopes that Mrs. Wilhelm was warmed by the ocean-side picture from Florida.
