The Universe's Mixer

The cards are white, simple, and comforting in their businesslike conformity. The raised black print is from a local shop, and Arthur only leaves them at establishments with expensive clientele, including restaurants with exotic cuisine, cigar clubs, Chinese medicine parlors, and purveyors of fine and collector's books. He asks permission to leave the cards and generally pays a small fee for them to sit in their little mirrored holders.

On one side, the card says:

CUSTOM DREAMS AND REALITIES
to your specifications

In small text, below, it says:

Clients must submit to full background check,
pricing upon request.

On the back, in the same black lettering, it says:
