I love original sign ideas in any shape or form.
When I Saw this book shops sign I thought it was a brilliant memorable sign idea, but the more I looked at it thinking, "how did they go about making this?" then I thought, "is this a just clever adaptation of a shutter box?"
I once designed a really cool sign for a bookshop, essentially a load of different size trays stood up like books leaning on a shelf… their "we want to stand out, want all singing all dancing" budget turned out to be foamboard from another company. 6 months later I was putting up a new sign for a pound shop!
I’d love to be more adventurous like this more often but customer budgets just don’t allow 🙁
