When I was going through the Free Library of Philadelphia's Mary Wickham Bond archives, I came across some bizarre stuff.

Exhibit A is this 1972 bill from a London dentist -- for 6.3 pounds. 

The language is wonderfully old-fashioned. They "beg to state their fee for professional services."

There still is a dentist's office at that London address (Harley Street Dental & Implant Clinic), but they have not responded to my emails. (Not sure they ever got them).

Mary Bond seemed to have all sorts of ephemera (thank goodness!).  The real James Bond not so much, although he was a bit of an Anglophile.
