silver lining (and gold rim)!

The only downside of my job is that there is no "little girls' room." (NB. This IS legal, long story...) There are some "public" facilities nearby and (needless to say) I'll wend my way there once or twice a day. When I got there today I was greeted by an annoying sign saying "closed for cleaning", so I decided to spend 5 minutes browsing in the Oxfam shop across the road. When I went back, the loos were still closed (worse, they were still closed 3 hours later, so I had to use the expensive ones at Park St car park).

But, it is true: every cloud has a silver lining (and, in this case, a gold rim, too) because LOOK WHAT I SCORED IN THE OXFAM SHOP. (I make no apology for shouting).
OK, so I'm a stepmother, as opposed to a mother, but that still puts me in the "mothers" category (and it gives me more time for knitting than genuine motherhood would, but I digress). Maybe this out-of-focus saucer might give you some idea as to why a non-tea drinker falls in love with a cup.
Needles and yarn, thimble and thread, killer heels... And on the back of the cup, a woman reading by a blazing fire (that's me that is, though I don't have quite such a shapely figure).
And on the front of the mug: yay! She's been caught knitting...
The cup is an oversize one of the "breakfast cup" type, the manufacturer is Fieldings Crown Devon, the pattern number 5599. Fieldings ceased trading in 1982, but I can't find any info online as to what date this might be from. Maybe 1950s?
I couldn't believe my eyes. I couldn't believe the price (and went and double-checked it with the manager) and the woman queueing behind me was very, very envious. Sorry the pictures are so poor, but I won't be at home during daylight until 1 Jan and I wanted to show it off now!
