Normally I interpret 7's as expansiveness, myriad of choices/opportunities/possibilities etc. and I think of the the cups as being about the emotions. So, the 7 of cups is 'traditionally' to me about daydreams, hopes, fears, and projections, born of emotion.
but, just looking at the Marseilles 7 of cups visually, I could see other things, too... which is why I love pips so much!!
That cup in the centre seems 'on display' to me.. so meanings might hinge around a prize, a performance, or someone being the centre of attention, or something receiving a lot of focus; singled out amongst others.
The shape of the vines also suggests a lyre to me, so maybe something about creativity, expression, beauty, or elegance.
If I look at it another way, those vines are like antlers protruding from the bottom cup. Wildness, impulse, ruggedness, nature?
What if I combine all those...?
There is an 'antlered' cup displaying another cup, inside of a harp.
This could mean that someone is getting a lot of attention(the central cup), because they appear to be the picture of charm and sophistication(the lyre); however the reason for this appearance is the contrast to someone else who is much more crude and brutish near them(the antlers). Perhaps their merits are exaggerated next to someone else's faults.. or maybe the other way, too; someone's faults are exaggerated next to another's strengths.
I am also looking at that top, central cup.. it appears to me that it could drop down at any moment to take the place of that one that is currently so prominantly displayed in the centre.
Whatever is on centre-stage in one's life, now, could be replaced just like that.
(This bit seems more apparent in the Dodal image that I'm looking at, where there are no leaf curlicues between those two central cups, and also there are little kind of 'pincers' coming up underneath the main cup, which threaten to nibble away at its base.)
