I wish someone would create a What's Lost app as I have frequently mislaid stuff and it can get rather frustrating to say the least. I've now lost quite a big picture called The Dinner Party by Jules Grun. I know it was upstairs out of the way but I could swear I brought it down and put it in one of the rooms. No, it is not hanging on a wall!
I have looked all over the place and under beds, cabinets etc, you name it. Maybe Growster could do one as I'd pay him handsomely.
