The Gaian aces seem particularly straightforward to me. The Ace represents potential, the availability of a new, creative impulse or energy. So, the Gaian aces feature baby animals representative of each suit.
The Gaian Tarot also helpfully abandons the symbols of each suit (Cups, Wands, Coins and Swords, moving clockwise around the above image) and instead just names them Water, Fire, Earth and Air. So, for water, a hatchling and some roe, for fire a lizard emerging from its shell beside flames, for earth, we've got Bambi and a fiddlehead fern, and for air, a newly-emerged butterfly. If you can't interpret those, what hope have you got, I say! So those fit right well.
I'm going to be 'musing' on each number in turn, but I won't be posting every card because I think that might be dodgy as far as copyright is concerned. So I will select samples. If they all go as easy as this, there'll be no trimming. Alas, this may not be the case. We shall see!
