The Field Notes Snowblind edition really deserves to be unwrapped and used outdoors. The white cover changes to blue when the book is bathed in the UV light of direct sunlight. I have never seen this effect. Placed on my windowsill behind double glazing and still wrapped in cellophane, even in the British midsummer the photochemistry has no chance of happening.
Update: We had some sunny weather so I removed the cellophane. The white covers that had been sealed inside turned blue immediately. It looks like the top cover had been deactivated (and slightly yellowed) by continual exposure.
The notebook on the right is a Silvine Memo Book (99p). Its front cover is the same colour as the ladybird on the left, but the back is “sunned” as they say in the book trade, with the faint pink shadow of a 50p coin.
The last element here is the Retro 51 Dr. Gray Tornado Rollerball pen which is luminous. It does write very smoothly and actually leaves the same line as a vintage Sheaffer fountain pen I bought recently. There are still some Dr. Grays available at the PenShed at the time of writing. The skeleton image is beautifully printed with a lacquer finish. Henry Gray wrote the book on human anatomy: ‘Anatomy’, published in 1858. Well, yes, there are other books on the subject.
