Telephone Credit Cards

In “Jerry Hulse’s Travel Tips” (Dec. 13) there was one item on using telephone credit cards in London and Austria. However, several other countries in Europe also have this convenience--Belgium, France, Italy, Netherlands, Portugal, West Germany and Spain. Details on using the telephones, including where to buy the calling cards and how to use them are included in “Manston’s Travel Key Europe.”
