V & A - the great teatowel mystery

Remember my post from a few days ago about Caren Garfen's teatowel design commemorating the V & A exhibition? A small envelope arrived in the post today, containing - one of those teatowels! The stamp franking is indecipherable (part of it might say "Windsor") and I haven't a clue who sent it - no card or note inside. Anyway, thank you very much! I'm going to hang it on the wall in my workroom once I've got the place a bit more sorted out and enjoy my "extra" time -

"ON AVERAGE, WOMEN SPEND TWO HOURS THIRTY MINUTES A DAY DOING HOUSEWORK, COOKING, WASHING UP"

EDIT - Mystery solved - Caren sent it (I suspected that might be the case). Thank you very much!
