Sophie Blackall's 19th century style mailing promotes her new picture book

I always love hearing about interesting and unique ways (without being spammy) that children's book authors and illustrators have for promoting their work, so was intrigued by Sophie Blackall's promo effort:

From Publishers Weekly (click on image to see original article)

The package above was mailed out to about 100 chlidren's book professionals, handmade by award-winning illustrator Sophie Blackall to help promote THE MIGHTY LALOUCHE, a new picture book about a Parisian postman at the turn of the 20th century, written by Matthew Olshan and illustrated by Blackall. 

What a wonderful package to receive in the mail!
