1890 Jubilee card, South Kensington large & Museum postmarks

2nd July 1890 Jubilee card with a South Kensington large postmark and the South Kennington Museum blue souvenir postmark. There were four special souvenir postmarks designed for use at the Jubilee Exhibition, as well as a postally valid South Kensington special postmark. These museum souvenir postmarks were all misdated as 1990 rather than 1890!
