Help With Determining Origin And Price Of Penny Black / Blue

Does anyone know where this framed Penny Black and Two-Penny blue comes from? Also, how much do you think this is worth? Thanks!

It is a buyers market at the moment, you have no chance of getting catlogue valuations, best advice is to hang onto it, until we all get out of the recession.
For an accurate evaluation you would need to determine the plate numbers and watermarks of the stamps.
The stamps come from England, the country that invented stamps and philately.

It is somewhat difficult to tell, but the Two Penny Blue appears to have white lines below the word "postage" and above the words "two pence". This means that it is not the original Two Penny Blue, but the modified design. It properly belongs with the Penny Red, the color of the Penny Black being changed fairly soon due to the difficulty of cancelling the original black color properly.

I do see that the date under the two pence stamp is 1841, which means that the creator of the sheet recognized that the two pence stamp was not the original two pence stamp issued contemporaneously with the Penny Black.

I believe that this was one the Stanley Gibbons "Investment Advertisements" In the Eighties.

Thanks for everyone's replies! Gibbons? Hmm anyone know what this symbol is then?

Interesting to note that Gibbons refers to the 'two penny blue', when it is in fact a two pence stamp.
Penny is singular, pence is plural.
Shows even experts can have bad grammar.
