You lost a bag of shopping in a museum.  Write a letter to the museum to ask for help.

Dear Sir or Madam:

I am writing to ask for your help in finding my lost bag of shopping in your museum.

I visited your museum late this morning after I did some shopping at the nearby mall for my daughter’s birthday.  I was so amazed at the African Art Exhibition that I totally forgot about my shopping.  No sooner had I realized that my shopping bag wasn’t with me than I hurried back to search for my bag, but in vain.  The bag of shopping includes some gifts for my daughter and a brand new tower as well.  Though there’s nothing expensive in the bag, it is very important for me and I would appreciate it if you could do me the favor to help me search for it.  It may either be handed in to your lost-and-found office or still be somewhere in your museum.

Please inform me whether you can find it or not, and my address and phone number are given below.

Sorry for any inconvenience caused and I am looking forward to your reply.  Any of your help will be greatly appreciated.

Yours sincerely,
