These 2 stamps, differing only in background colouring, is from a Brazilian sheet of 20 stamps released on 24 March 2015, as the first of a 3-series stamp issue leading to Rio 2016 Olympic Games. The sheet of 20 stamps contains 2 sets of stamps featuring 10 sports, rugby being one of the sports; the foreground designs featuring the different sports are similar, but the 2 sets of stamps are printed on a sheet with a unique background, hence giving a result of 2 sets of stamps of different designs. This scheme will probably be repeatedly for the remaining 2 sets in the series.
