Stationery evolution

I have produced the artwork for the stationery for this company for over 12 years through 3 different name changes and 5 different identities. It comprises not just the usual letterhead, comp slip and business cards, but also a long list of labels, stickers and inserts for items such as CD cases, presentation documents and wallets, VHS and Beta tapes and cases, document covers, even carrier bags.
Shown here are the four early identities. Guidelines for the current one can be found here.
Please note the lovely thank you letter addressed to me which reads:
"Dear Jane... The brand launch, without doubt, was our best ever... An enormous amount of credit for the success goes to you, because without your hard work and professionalism it would not have been possible.... [we] found working with you very reassuring. Yours is certainly a job where patience and unflappability are a bonus and you have it in abundance...."
