Focus on Forgeries

Linn's Focus on Forgeries: A Guide to Forgeries of Common Stamps was published in 1993 by Linn's Stamp News.

This useful book by Varro E. Tyler lists 150 stamp forgeries from A to W, side by side with the genuine ones, and compares both.

The introduction states in part that "This compilation of 150 Focus on Forgeries features that originally appeared on a fortnightly basis in Linn's Stamp News is published at the request of many stamp collectors."

Illustrations are in black and white.
