So if you go to that page that tomkin gave you, and make a note of the reference on that page:
Title: Postcard showing Young Samson the British Goliath at Headley's Famous Shows.
Reference: BDSo 44/14
Then press the "
See Contact Details" button on the page.
It will give you the contact details for Cumbria Archive and Local Studies Centre, Barrow
It gives you their opening hours, address, email address and phone number.
If you contact them and ask if it's possible to see a copy of that postcard then I'm sure they will be more than happy to help you.
Also, if you can give us as much information as you know about GEORGE ROBINSON then we might be able to find some information for you ourselves.
For example, date of birth, date of death, and baptism dates, marriages, and where he might have been. We're in Bury ourselves, and I'd be more than happy to go down the records office in Bury if you let me know what I should be asking or looking for.
For the post card though, you'll need to contact Cumbria Archive and Local Studies Centre, Barrow using the details above.
Let's keep looking
