where the month can be omitted if you do not know it, and the year could be indicated approximately (for example in the form 192x) when it is not known precisely. The model can be omitted if the advertisement is generic, and if more than one appears, use the name of the most important one. Words must be separated by hyphens and the short description must be used to distinguish advertisements of the same period and stay within the 2 words; an example is: <tt>1908-Waterman-GiftSanta.jpg</tt>. | where the month can be omitted if you do not know it, and the year could be indicated approximately (for example in the form 192x) when it is not known precisely.
