There is no imperative to love art, but if you do there is a way of feeling that joy on a daily basis, and that is to collect art. If what you are into is old masters and modern art rather than contemporary art, then the practical way to collect is to buy prints. Original prints and drawings allow one to collect works of many of the greatest artists in history, something no longer possible with paintings or sculpture. You cannot collect Rembrandt paintings today. You can collect Rembrandt drawings only if you are a multi millionaire.  But you can collect Rembrandt etchings. They may not be dirt cheap and some may be quite expensive, but they are available. An amount in four figures will buy a good Rembrandt etching: five figures will buy a very fine one. Unlike paintings and sculpture of the great masters prints are available, and posthumous impressions are an affordable alternative.
One generation's famous prints or artists are not necessarily another generation's famous prints or artists. Rembrandt’s and Dürers go on and on (though the comparative value of particular prints may change), but the prints of the 1900 hundreds that brought fabulous prices are largely ignored today, and some prints and drawings selling today at high prices - though obviously minor figures in art historical terms –are well calculated to be forgotten tomorrow.  The collector needs to be able to distinguish importance from fashion, not always as easy to do as it sounds.

Unless you are a walking encyclopaedia there will always be artists you have never heard of who nevertheless will have produced good or even great prints or drawings. Consider that ubiquitous artist Anonymous. Virtually every museum in the world has at least one masterpiece by him (or her). The single most important thing about a print or drawing is whether or not it says something meaningful to you. It is ultimately more satisfying to buy a picture because it appeals to you than to purchase a Picasso or a Manet that you don’t even like but can get relatively cheaply.

Obviously, buying a print or drawing for the lowest possible price is desirable. Apart from contemporary published editions of prints, there is no “list price” for prints. The right price, therefore, is simply one that is agreeable to both buyer and seller. A dealer usually sets a price based on what he thinks is fair market value. Different dealers have different thoughts on this matter, although the variation is frequently less than you might think. Other factors, such as, the dealers actual cost, whether they like the print or not and whether they have more than one copy of the print, will affect the price the dealers set.

Many new collectors target editioned prints because they have an idea of their scarcity. However, with rare exceptions, artists and print makers only started numbering prints in the nineteenth century. Before that, the edition was limited naturally by the deterioration of the matrix from which it was printed, so the first and last impressions off the plate look very different from each other. The number available on the market, in other words it’s rarity, and the quality of the particular print will determine it’s value.

If the experience of aesthetic pleasure is what inspires you, then, collect what interests you and pleases you and is within your means. Only you know what you like. If you find you are fascinated by a particular kind of print or drawing, specialize. If not, then don't. A generalized collection may make less sense to an outsider than a specialized one, but it will make sense to you and it will give you pleasure for years to come.
