An interesting question!

Sure, it is a good idea to contact other Keepers, we give you such an opportunity, and, it makes perfect sense, as the joint activity of the Keepers will contribute to the rising value of all individual Art Objects - CEAs or VEAs.
Just send a message and we will forward it to all other Keepers, and send you back any replies - then you can take it from there.

Many more options are possible, in time, a Forum, an annual reunion in the mountains or by the seaside etc - the golden rule is: keep communicating...
