So, it appears the mail is slow. Or, at least, that's the only logical explanation for it, because I've not received a card in a few weeks now, and my cards seem to be taking forever (20 days or more!) to get to their destinations.
Because of that, I could only send ONE card during week 21 of the "challenge" as I'd maxed out my limit of travelling cards.
This card is of an Australian Native Orchid and is (still!) on its way to the USA (AU-346363).
I sent TWO Postcrossing cards this week: Irish wisdom is on its way to Germany (AU-347840), whilst the medieval art is travelling to South Africa (AU-347841).
