These stamps are the peel off and stick on variety. I have no idea how well this sort of stamp will stand up to the test of time compared to paper and glue stamps. I assume this subject has been discussed in stamp collecting circles, which I don't follow.
Same sort of consideration regarding the stability of paper over decades. Some paper from a hundred years ago holds up better than paper from a few decades ago when paper produced by an acid process became more common in all but archival quality material.
Computer data storage may prove the most ephemeral of all, as changing formats and technology make things unusable.
On the other hand, there's a lot to be said for enjoying the present and not worrying about the past. :-)
Other places where you can find cartoon characters are on Disney stock certificates and the Pixar stock certificates. The latter are no longer easily available as Disney bought Pixar. Pixar used to send out large posters showing characters from future movies such as Toy Story 2, but stopped that, presumably when they had more shareholders and had to worry about mailing costs.
Disney switched to paying dividends twice a year rather than quarterly because they had so many people who only held one share for the certificate that the mailing costs added up.
This is a stock message board, so this isn't totally off topic.
www.oneshare.com shows the DIS certificate, as well as a Dreamworks certificate with Shrek on it. It's an expensive way to buy one share of a stock, so I am not recommending it, but it shows pictures of various certificates.
