Thanks for the kind words guys. There are some things you can do (and things to avoid) that will definitely help you.
-Latex and foam latex items should be kept out of sunlight (or any light that emits UV, like fluorescents).
-It should be handled infrequently, as the oils from your skin can accelerate break down.
-I'd recommend putting it in a display case to keep dust (and, as an added benefit, fingers!) off the piece.
-The form Capedcollector mentioned really is one of the keys, IMO. Foam will become less pliable over time and having it properly supported so that it still looks great when the time comes that you can no longer reshape it is really important.
-You should also aim to maintain stable humidity where you display the piece (I aim for 50% humidity year-round for my personal displays).
If you want to do anything further (such as having a custom form made, a display case made, or address any already deteriorating areas or damage) please visit our site (click the banner below) and feel free to drop me an email.
Hope that is some help!
best,
