From Heleen, personalized

[FinnBadger]

IN 2018 I received an envelope mailed with a stamp where Heleen has used her own design. It seems like more and more post offices allow you to customize your own design. Here in the US this is licensed to a couple of companies (and you are charged extra for it).

 

I doubt any of these designs are truly collectible, but you never know.

Heleen's envelope came with an added snail, as well as a fun December stamp.

 

Inside was a stripy banana - thanks for the fun mail, Heleen.

Those are fun, MomKat. Collector's item :)

The Dutch Post is so cool! 'luv Heleen's stamp and snail :-)

Years ago, the HELLentic Post had a stand at the Expo here in Thess,

and we could get a photo printed on Greek postage...

but it was expensive and limited to 10-stamp-issue-sheet only:

Also, in 2014, was the only brief time that we had self-stick stamps:

now we are back to lick 'em - stick 'em,

...but they are rare, so collectibles, yes?

They are ABSOLUTELY collectible!  Before the USPS offered custom stamps, there was a brief trial period.  I had a sheet made during that time because I knew not many would be ordered in the limited time for the trial; miniscule compared to the usual printings of regularly issued definitives and commemoratives.
