Signed Mccloskey, Jr. Plate Blocks

Looking for any expert input on these 3 plate blocks. Two are signed by McCloskey as the "modeler" with both picture engraver and letter engraver signatures.

What type of information are you looking for?

Victor McCloskey was a prolific stamp designer/engraver for the USPS. The Smithsonian's bio for him says,

Victor S. McCloskey, Jr., studied at Corcoran Gallery School of Art in Washington, D.C., located just a few blocks north of the Bureau of Engraving and Printing. After completing an internship at the BEP in 1926, he joined its staff as engraver (1930) and then designer (1934). Designing the first federal duck stamp was among his earliest assignments. He spent his entire career at the BEP, retiring in 1965.

His signature (and others) can be found on many of the stamps issued during that period. There is a collection on ebay right now with about 200 different plate blocks for $750, to give you an idea for their valuation.

I don't know whether those specific airmail plate blocks the you posted are worth more or less than the average.

If you search the SCF forum for McCloskey you can find a few references to his other work, in particular the "Collecting by Engraver" thread,

Thank-you. This is basically what I needed to know.

Thanks for the link to the signed plate block collection. I liked it. I bought it.
