Brooklyn Chess Chronicle, v. 4, i. 5 (1886-02-15), p. 79, tourney prb. 7
The problem won '2nd prize for 2#', but in difference to the 1st prize for #2 it was not awarded by the judges, who did have the authority to do so. Instead they gave the problem a honorary mention, and the tourney management awarded it the '2nd Pr. for #2'. (2022-12-15)
