... requiring a lot of high spirit and nerves!
Quality and not quantity is a definitive goal but enthusiasm and passion usually makes quantity triumph specially when we start our collecting journey but also during a great part of the road.
In any case, I feel that reducing such a fine collection like yours with so many desirable pieces to "just" twenty pieces will be not an easy task an will require a lot of planning and hard to take resolutions.
I wish you all the best of lucks in your project my dear friend and that you will keep enjoying your collection so much and with same passion.
Abrazos desde las Pampas! Abel.
