This is a treasure I've carted around through moving house many times...I can't remember where I got it, maybe the dearly departed Rainbow op shop. It's a little pack of cards for identifying birds, with beautiful watercolours and descriptions on the backs:
I really like the idea of slipping these into your pocket if you're going out birdwatching. The packet says the series also has wild flowers, British wild animals, and dogs. Now doesn't the idea of carrying around cards for identifying dogs seem creepier somehow?
