This invitation was inspired by a replica of an old, intricately cut, Victorian-era valentine. The structure of the popup mechanism was used as a starting point, but the design needed be produced using a paper cutter and scissors, which lead to the geometric theme.

The red square reads: "Don't miss out! Or you might turn into a TROUT!"

The white circle reads: "Come and Print! Come and Play! Buy some Art! Stay all Day!"

The orange triangle reads: "Attention! No-shows will rue the day of their wickedness and repent! Attendees will witness the bright beauty of original prints and paintings, experience the heady thrill of producing artist ephemera with archaic heavy machinery."

The yellow rhombus reads: "Warning! Failure to attend may cause headache, nausea, aching, dry mouth, fatigue, polka-dot tongue, lunacy, forgetfulness, and green-nose, similar to sugar pill. Attending is likely to cause a euphoric sensation associated with an invitation to ink a plat, turn the wheel of the Griffin Company etching press, and peel back a glistening newborn print. Or to crank the handle of the 1100 lb. Vandercook letterpress and extract the crisp, exquisitely embossed card from its drum."

The purple diamond reads, "Caution! Not attending may cause bad parking karma later in life. Accepting this invitation will bring you great fortune. Especially on that future day when you need a special invitation or announcement and you know exactly who to come to for unique, imaginative work. Or when you want to fill that empty space on your wall with something stimulating, something that takes you outside of your room to a faraway place. Or when you'd like to nurtur your own creativity with a supportive artist at your side."

Five richly colored Lokta papers were chosen, with a puffy Laroque Colombe used for the circle. This was the last Open Studio invitation in which Vanderheiden enclosed an original print. A three color wood engraving was carved in Resingrave and printed on vellum. This was a very baaaaaadddddd choice! The ink would not dry and could not be absorbed by the vellum, but the invitations needed to be mailed. The stove, microwave, and clothes dryer were all enlisted to help, but the results were frightening. Most prints have inky backs and an interesting scratch effect on their fronts. The ones with burn marks were discarded.

From 1999 to 2005, Vanderheiden participated in ProArts East Bay Open Studios. Each year, limited edition handmade, letterpress printed invitations were made for clients and supporters. These invitations are no longer available through the studio and are now collectors' items.
