Would anyone know what years there would have been 2 and 3 digit phone numbers? I recently found The Little Red Book of Household Hints, Price $1.00 Printed by the V.F.W. Auxiliary of Emmetsburg, Iowa. I will later transcribe a list of the women's names and the advertisers. The date this was published is not given, but the ads all have 2 and 3 digit phone numbers. Some of the helpful hints are pretty interesting (i.e. funny) and I will also transcribe some of those for your enjoyment at a later date! Cathy
