3 April 2017 Post Office Railway digitally printed Post and Go stamp on single-design roll.
Only available at The Postal Museum.
This was probably intended to coincide with the opening of the new Museum in the spring of 2017 but the opening was delayed. Nonetheless the new stamps were added to their machine while the Museum was closed.
According to Stamp Magazine (June 2017, p23), no stamps were sold on the day
that they were added to the machine: this was because there was no announcement by Royal Mail, nor by the Museum.
