Sub-Series 60-61

Not quite sure what was about to happen here. I guess after the planes and birds, it was time to draw some sort of a puzzle? A story in questions? I think the little drawings might be the various arts. The first one looks like a canvas, or a piece of paper. The second one looks like... hmm. The third one is definitely sculpture, because the fourth one is acting. Then the 5th one must be the art of writing letters. (Lawyers are good at that.) The 6th one is architecture. 7th-cinematography, 8th... Photography (always with a white rim.) 9th is the art of being able to make a plant survive. 10 must be the art of love. (Or something.) 11 is television design. 12 might be music? (hehe). 13 looks like the art of writing letters, which would make 5 just good old mailart. 14 is probably... hmm... a chair... industrial design? Or could 15 be it?
16 is the art of getting somewhere. 17 is just a silly plus sign maybe. The cat could represent the art of being a pet. 19 is some sort of world thing, the web?, a blog? 20 is all that can be ultimately packed on the pages of a book. 21 contains all your phantasies. (Or just an al dente piece of pasta, thus the art of cooking.) 22 is the art of hmm, responsibility. 23 is the art of driving under the influence of love. 24 is the art of staying afloat. 25 is pure fire. 26 is a bit like 16, but slower. 27 is the art of inspiration. 28 is everything else. 29 is the art of not getting upset that that the most important arts did not make it onto these pages, because it is the most beautiful thing when certain things are just not there. 30 is the art of happiness. Still do not know what 2 is.
All of the description were an attempt to describe the page. At 9:03 still at home, late for the train... aaargh... now it is your turn. At least tell me what 2 is. Thanks.
