This is not une penne

[FinnBadger]

Great envelope in from Eric. With the IMB in an odd place.

Fortunately they peel off very easily.

Eric also does  great job of designing postcards to send in his envelopes. The cards usually advertise his site in a fun or interesting way.

IMB stand for Intelligent Mail Barcode

I have recycled IMBs into mail art in the past. For the Parallels project.

You can recycle that sticky US postal bar code, dear Finnbadger, onto other mail art,

oh yes! (that USPS robot machine keeps on sticking them everywhere, eh?)

which is also a "type of penne" :-)
