Together with all the memories as one of seven friends who joined the Women's Land Army from their home town of Holyhead, she has a Royal Doulton figurine in the WLA's green and brown colours holding the trademark pitchfork, which also brings back those times of 'digging for victory.'
"It was given to me by my late brother, Bill," recalled Mrs Hartley at her Plessington Court flat in Longridge. "It was a surprise present which he thought I should have to remind me of what I did for the war effort."
And now, of course, with the recent national recognition by the government of that effort by both the WLA and the Women's Timber Corps, she has another prestigious memento - a citation from the prime minister and a copy of the badge all land girls wore in their felt 'slouch' hats.
"These bring back so many memories of very hard work over four and a half years - but we also enjoyed it all!" she laughs, remembering that she became a land girl only because her grandmother forbade her to join the WRNS - the Womens Royal Naval Service.
"By then all the men in the family were in the Royal Navy or Merchant Navy - she didn't want me to go as well!"
With her friends, Mrs Hartley was stationed first at Penrhos Hall near Holyhead, a town targeted by the Germans as it was on the shipping route for convoys, and a harbour for ships which had been torpedoed.
"I cycled two miles there and back every day, and we worked at everything - milking, threshing corn, sawing logs, ploughing, planting and picking hundred of potatoes, sprouts, cabbages, in frosty winters and long summers with double summeretime then.
"We even had to kill rats, and we worked with shire horses... we were tough old birds really!"
Mrs Hartley then moved to Merionethshire, billeted at a small farmhouse but working at a private house where the head gardener, one Mr Collins, "worked me to death!" she remembered. "Everything grown went to the house - the owner supposedly went down with the Titanic - and I ate my dinner, a cheese sandwich with one saccharin in my tea, in the servants quarters."
It was at Penrhos Hall, however, that the young Myfanwy Evans met her fufure husband, Roger Hartley from Preston, who was part of the battalion of soldiers billeted there.
"I went out to get my bike one day and couldn't find it - until I saw this soldier with it in bits on the ground! He said it needed mending, which he did - and then he asked me out!"
They married in Holyhead, settling in Longridge where Mr Hartley - who died 20 years ago - opened his carpet business, Hancock and Hartley, in Berry Lane.
The couple brought up their five children in the town, and Mrs Hartley - who has nine grandchildren and three great grandchildren
