MMSA envelopes received - part 4

I received this envelope fashioned from the insides of multiple security envelopes.

The texture of it made me think of the intaglio Inverted Jenny $2 stamp.

Sent to Jean.

And the back.

The final one in this series is made from an art catalogue turned on its side.

I liked the colors and energy of the Tito Puente stamp for this one.

Sent to Hester.

The back.
