Hello AngelFish
I have two or three postcards with flower decorated bicycles. One is of my grandmother. My father said she won the first prize with her bicycle.
She was a Methodist and I think these were sometimes done at the Temperance rallies, around 1908. She was at either Woodhall Spa or Billinghay Lincolnshire.
Loved the postcard of the children, the date is 1914 and it looks like the postmark is Bourne in Lincolnshire.
The postcard of the older couple, on the back in pencil it could be an abbreviation for Sheffield, along with the numbers.
Regards
Lulis
