This collection consists of a portfolio of wet collodion portraits of new immigrants to the United States by fine arts photographer Jill Enfield. The portfolio forms a part of Enfield's The New Americans series, and originated as a year-long project funded by a Faculty Development Grant from Parsons. Enfield's grant statements are also part of the collection.

The collection consists of 53 handwritten letters from Richard Tweedy during his time in Holland with William Merritt Chase's 1903 summer abroad program, and from a later period when Tweedy lived in Paris. (One 1906 letter is from his home in New Hampshire.) The letters are mostly addressed to Tweedy's mother, Mary Alice Belcher Tweedy, while a few are addressed to his brother and to his father. Typed transcriptions of each letter are included.
