Final answer:
The provided references do not include information on a character named Mattsson; therefore, it's not possible to accurately determine what Mattsson left for his wife after his death.
Step-by-step explanation:
The information provided does not directly answer the question of what Mattsson left for his wife after his death as there is no reference to a person named Mattsson in the given passages. These passages explore various gifts, tokens, and legacies left by or for different characters in unique circumstances, yet none correlate to a specific character named Mattsson. The gifts mentioned across the texts vary from toys, marble slabs for a grave, a purse clasp, rice to the government, and a letter announcing death, but none of these seem to match the options given in the question about Mattsson's bequest to his wife.
