It is puzzling.
The Guardian article from 2019 said "The major crime review team recently came upon two postcards", "The tear-off postcards are from a calendar sold by..." and "Avon and Somerset police say they cannot spell out how they got hold of the postcards"
The Mail article said "Police were keen to speak to anyone who may have bought this calendar or who kept the tear-off postcards with these specific images, possibly for some time."
They do not look like they were photographed in June, the day of the murder, with the autumn colours. I suppose they could have been taken previous autumn and developed and sold after the murder.
I think it's more likely they were sent the postcards by the killer, and they want to know if anyone knows who kept them from the 80s/90s, or they are appealing to the person who sent them because that person knows who kept the postcards.
