Wall-Mounted Display Case
A prefabricated display case is one good way to display a jersey. Among the more useful features of this particular case are holes marked for attaching it to the wall and a dowel for hanging the jersey; the dowel slips through the sleeves of the shirt and then is suspended from a hanger within the frame. This technique allows the shirt to be exhibited with much more dimension than could be achieved by simply hanging it on a hanger.
After determining which side of the jersey he wishes to display, insert the dowel through the sleeves. This case is deep enough to allow the jersey to be displayed with some dimension, but it's possible to find or build cases that will hold considerably bulkier items.
One alternative to the dowel idea is a custom display cases that can be made from wood and lined with fabric, to which the display item can be pinned or, alternatively, affixed with hook-and-loop tape.
Proper lighting is important. Memorabilia should be lit in a manner that prevents damage, as many materials are highly susceptible to the effects of UV rays and should be protected from them. Among the types of lighting available for displays are rope lighting, which can be mounted on the inside of deeper cases for added glow; and museum lights that can be wall-mounted above a display case. These can be used alone or in combination with other methods.
Another important part of displaying any type of memorabilia is attaching a plaque that explains or commemorates an item's significance. Remember that although an item may be of great importance to you, it will have an impact on others only if they understand what it represents.
The best way to approach a niche display is to make sure it isn't crowded -- items are of interest only if they can be seen clearly.
