MMSA Asemic Writing part 1

Here are two I sent in for this fascinating MMSA challenge. The silver 'writing' doesn't show up very well on the scanner - you may get a better view by clicking on the images to enlarge them.

And two I received from Rhonda and Christie.

They both used vintage stamps, neither of which I've seen before.

And on the topic of stamps, the USPS online store is now offering variety packs of 20 random forever stamps. Interesting concept.
