Collector HENRY has collected signatures for more than 30 years and is keen on collecting various autographed items. He has been participating in trade shows all over the country. While buying and selling autographed souvenirs, he has more interest and enthusiasm in researching autographs, and slowly developed into a career and compiled a huge autograph sample library, has become a senior signature appraiser and a leader in the signature appraisal industry.

HEA has accumulated a large database of samples that signature verification workers use to accurately assess the thousands of signatures submitted each day. Our boilerplate database is an important tool we use in validation.
