USPS issued a set of 10 stamps earlier this year based on illustrations from gardening catalogs originally used between 1891 and 1910.
Here are some sent out on envelopes 789, 791, 796 & 809.
I showed a few more of these stamps in a previous post.
And here are two that I received in Jean's April exchange.
Pretty flowers from Amy.
Watercolor and calligraphy from Thomas.
And Thomas included this neat wax seal that traveled perfectly (amazingly) through the mail.
To see more flowers, head over to Sunday Stamps.
