Heartfelt thanks for stamps!

A surprise parcel arrived containing many thousands of stamps sent by a friend who was having a clear-out! The majority were red 1st and blue 2nd class stamps,  1st class gold stamps, and  hundreds of Christmas issues from recent years.  All of these will come in useful in stamp collage pictures including some I am currently working on.  But there are also several little treasures  amongst the hoard, and here are just a few rather special stamps which may be part of something in future.
I have mentioned the Resplendent Quetzal in a blog of 27th July 2019,    and so I was thrilled to uncover an old Guatemalan stamp issued  in aid of the Red Cross, featuring a nurse flanked by two of these wonderful long tailed birds. There is no value on this stamp and I haven't yet been able to find out exactly when it was issued or if indeed it has any current value, but will keep if in  my/my father's collection of very old Guatemalan stamps!

I always love to find a heart!  And there were a few among this enormous pile of stamps, so that made me very happy!  I have a growing collection of pretty heart stamps from several countries, and any duplicates can of course go into a Love themed collage at some point!
