ways to organize my collection

Here is an example of how I can organize progression in how a certain pez is remade over the years.

Here is an example of how older pez do not have feet on the bottom v.s. the new pez who have a footed bottom to them.

I could also organize pez according to their character groups. Like pirates of the Caribbean.

I could also do an organization based on color of the stems.

A new discovery I also made is I could organize based on location made. Each pez has the location in which it was made and I have seen several different locations such as Austria, China, Hungary, Slovenia, ect.
