Hi Cobweb,
Great to meet a fellow Pirelli collector! Welcome back. I have looked through your photos and some of them I couldn't see well enough to be sure, but here are my opinions. But do please buy the book - its the only way you can be sure and we have taken decades (literally) to make it comprehensive. So here goes on your pictures:
Starting with the first one that comes up, showing a fish, dragon, and a sort of thingy. None of those are Pirelli.
Pic 2: Rhino - not Pirelli
Pic 3: lots of things that aren't Pirelli but there's a Pirelli lobster in there, and what could be a Komaromy ostrich.
Pic 4: I can't see any Pirelli - not very clear
Pic 5 and 6: a Pirelli chimpazee, but it isn't very clear. You should compare it to the one in the Pirelli book on page 70
Pic 7: Not clear - can't see any Pirelli's
Pic 8 and 9: not Pirelli
Pic 10: Could be a Pirelli peacock - not very clear. Compare to Pirelli book pages 74 & 100
Pic 11: Pirelli scottie dog and probably a Pirelli ass (see page 63)
Pic 12: whole bunch of Pirellis jumbled up together - can't see very clearly
Pic 13 and 14: Pirelli HIghland bull (see page 99)
Pics 15 and 16: Probably Pirelli hippo and bronto (xee page 75)
Pic 17, 18: Not v clear, mostly not Pirelli but could be Pirelli frog and fox (see pages 67, 68)
Pic 19: Can't see any Pirellis except Chimpanzee. Not v clear.
I hope that is helpful.
