"This book is a description of what is, so far as the Author is aware, a new kind of hobby, but one which seems on the face of it to be as reasonable, as interesting, and as instructive, as any other sort of collection fad. This is the collection of street-car transfers and allied forms. The Author himself has already collected over sixteen hundred such forms, there being no duplicates included among that number; and he has found the process of collection, and the things observed during the process, both interesting and entertaining. He believes that others could get the same interest in such collection, even though it were made on a more limited scale." The media industry, believing that this was his only book, proclaimed it evidence that Sidis had "burned out."
