San Marino stamps from 1991, available online at Io Collezionista. The issues placed in this San Marino Stamps subcategory belong to the window between 1 January and 31 December 1991. Among the most interesting stamps in the Io Collezionista catalogue are a lot of stamps from 1991 (complete set of 5 values) dedicated to moments of everyday life, 12 stamps from 1991 (complete set of 3 values) dedicated to the Barcelona Olympics, and 8 stamps from 1991 (complete set of 2 values) marking the centenary of basketball. The main Stamps category leads to the Vatican Stamps and Italian States Stamps subcategories: San Marino's own issues began in 1877, and before that year the state relied on Vatican Stamps and, earlier still, on Kingdom of Sardinia Stamps.
