I have no boot logo. Instead of the boot logo I use "the last read page" setting. This way, when you switch off the reader it makes screenshot of the page you are reading and when you switch it on, you are presented with the picture of the last read page until the book is loaded.
As a shutdown logo, I use picture I have downloaded from Russian pages here:
I use the logo that is next to the logo with Christmas tree. It says:
- Будешь больше книг читать, меньше водки будешь жрать
- The more books you will read, the less vodka you will drink.
- another possible translation is command: You will read more books! You will drink less vodka" The Russian text can have those two meanings with a few shades in between. This might be a reason I find it entertaining ;-)
Also the very first logo is nice on the page above. It is a poster that was used in very early Soviet days. It says that: if you do not read, you will soon forget your [freshly acquired] literacy.
I have posted the link in my review thread here:

If you have a picture and you want to make a logo you can use following web app:
